RCA harness Pins too loose to align with car's harness.

I have to give this a bad review because the pins in the square end of the RCA harness are very loose. It would not interface with the cars wiring harness. Because they are so loose, they will not align and connect properly.

Waste of time

Poor quality, pins do not stay in place. Absolutely junk! When plugged in u can forget about fader and balance? I ended up deleting my factory amp-took longer but the stereo works correctly. Don't wast your money on this! Overall, I'm very happy with this company and the stereo I purchased. This plug? Useless and u will be disappointed. 95 Mustang GT stereo upgraded.

The Trick gets it Done

Worked exactly like expected. But the reviews are right, the black square connector on the RCA adapter isn't great. The pins are loose, and are hard to get lined up properly. What I did to ensure correct placement was cut down the sleeve around the loose pins to expose them, and then carefully plugged it into the car's stock harness! Worked like a charm. Just be aware and be careful.

The black speaker plug is the worst .. all 8 pins move around and don't stay in.. It's also impossible to line the pins up to plug into the factory plug on the truck. Without modifying the plug it's impossible.

Metra 70-5510 Receiver Wiring Harness

This RCA wiring harness needs a serious redesign. The wires inside are somewhat loose, and it's almost impossible to seat the connector without serious modification to the connector. Initially I was only getting sound on the driver side of the car, but after reaching out to Crutchfield I had to cut a section of the connector out at which point I could see and guide the pins in correctly. Would have given one star but giving an additional because the other power harness was fine.

Metra 70-5510 Receiver Wiring Harness

The connector for the power leads worked, but the 8 pin connector for the speaker output to the factory amplifier was cheap and flimsy. I couldn't get all 4 channels to work at one time. I would get a channel with no balance or fader control. It looks like the connector pins were not staying straight when connecting. Pins even started to push out the back of the connector. I wound up snipping off the connector and the factory connector, then hard wired the 8 leads. Worked fine after that.

Metra Speaker Plug-in

The piece that was wire with Ready Harness service was perfectly fine (main wiring harness), but the piece that plugs into the RCAs and goes into the speaker wire arrived with already misaligned pins, and after carefully attempting to plug in the factory wire some of the pins got pushed out and now I have half of my speakers being powered.

Well it ended up working

Just like about everyone else the connector for the RCA plugs really needs some improvements on the end that goes to factory plug. After spending way to long trying to get it to plug in right I finally cut one side out of the plug so I could manually align the bottom row of pins to plug into factory plug. Then wrapped it with black tape so it would not unplug. The main plug for power was fine and the wiring instructions for Crutchfield were very easy to follow.

Extremely poor design

Crutchfield originally shipped me the Metra 70-1770 Receiver Wire Harness after telling me I could install it in my father's 1998 Mustang and bypass the amp. When I tried to install it, there was no matching connector for the audio wiring harness, and after talking with Crutchfield on the phone they apologized for their error and shipped me this harness for free. When I asked the Crutchfield rep if I could use the gray power harness from the Metra 70-1770 kit I had already wired up, they said that yes I could since they were identical. When I received the 70-5510 replacement harness, I realized that what the rep had told me was not true, the gray power harness for this kit contained an extra blue and white wire that was needed to provide power to the amp. When I tried to install the black audio harness however, as other reviewers have noted, it was simply impossible. The pins inside that harness are free floating, and it's just not possible to align them all and plug into the female adapter. Whenever you get some of the pins aligned, the others end up sliding above or below where they should be so that you end up with partial audio. I finally used a screwdriver to push each pin out the back of the plastic harness, and plugged them in one-by-one to the female adapter. I can't believe Crutchfield sells equipment of such poor quality.

Buy the amp bypass harness instead.

Pins in the speaker adapter push out the back when you plug it in, rendering the adapter useless. I had to buy the factory amp bypass wiring harness to make everything work.

Metra 70-5510 Receiver Wiring Harness

This kit allows you to connect an after market radio to the stock Mach 460 sound system in a 1996 Mustang, which it would be great for doing, however I had an issue with the pin connector. When attempting to push the pin connector on this unit into my factory connection, all the pins pushed right out of the back. This made the piece relatively useless - I had to cut off the factory connector and the pin connector on this harness to run the wires. I've installed 20+ radios over the years, and this turned into being one of the most difficult, had to figure out color codes for all the speaker wires on the factory harness. I'm sure I could have contacted Crutchfield for a replacement, but I figured it would be faster to just deal with it. Maybe I ham fisted this, but I really don't think so. The connector for the radio to the factory harness was fine, the only issue was with the connector for the amps on the factory system.

not good unless changes are made

piece is cheap, pins not mounted very sturdy. when installed the first time, several pins pushed out but was able to get back in, now after having to remove stereo while working on something behind the dash, pins pushed back out and wont align again so no sound from stereo which really sucks

bad bad bad

Main harness was fine. The amp output for the rcas is awful. I wish I'd seen these reviews. Why does Crutchfield continue to sell the obviously bad product? Because people keep buying it? Says alot in of itself... I bought a 70-5511 harness and the plug was so much better .of course it doesn't work for this application. So now I've got to try and cut open the RCAs and see if i can wire that. Overall , this was not worth the money. I paid for the service too. 50 bucks down the drain for a project going on 3 days and counting. After seeing this was a known issue , and sold to me anyways, will be my last purchase with Crutchfield. I left a review on the service page and the response was " support was available 24/7" which unless a new magical wiring harness appeared out of no where, i don't see what talking to someone i can barely understand on the phone would help at all. Just completely disappointed

The power harness worked perfect. The pre amp harness is useless. Crutchfield was nice enough to send me a replacement, that one didn't work either. When you look in, you can see that the pins are not close to straight, pointing in every direction. And nothing really holding them in place. I can imagine how anyone could get all eight of these to align when plugging into vehicle harness.

Metra 70-5510 Receiver Wiring Harness

It connects, the 8 pin? black prong is something else though. I pushed the connector together and was only getting sound out of half of my system. You can't see the pins and they're way flimsy trying to align the connections blind due to covers shrouding them. I ended up taking a Dremel and cutting the protector/ cover back, just enough to see the pins. This way you can see the holes and connectors are aligned when going together and it worked like a charm. a couple of zip ties to secure the two connectors as I cut the locking tab off and retested.

Cheap product

The 8 Pin receptacle caused me issues... The pins move around making it hard to line up with the vehicle wiring harness. When you push with minimal pressure the pins come out the back, and the wires break very easy. Crutchfield had to send me 3 different harness, all had the same issue. This delayed my install 2 weeks until I got the third harness.

Remove pins from amp harness/ plug in the connector/ push in pins

Used this to hook up a new receiver to my stock Mach 460 amps/speakers in my 95 Mustang GT. The connector for the power connections is great. Directions mention no need for two of the three orange wires. As for the amp-to-RCA jacks harness, it is unlikely to just fit. I did find it was pretty easy to pop all of the pins out using my t20 torx bit driver, clip the black plastic Metra harness onto the amp harness and then insert the pins, seating them in with a small flat head screwdriver. The wires plug in he following order from left to right with the clip portion on top. Black/Purple|Black/Gray Black/Green|Black/White

Simply Didn't Work

This harness simply didn't work. Crutchfield service was great. With the first harness, only the two left-side speakers would function. Crutchfield replaced that harness with no questions asked, two-day shipping. With the second harness, three of the speakers functioned but not all four. We were able to cobble together a solution using different elements from the two harnesses, so the overall result turned out okay, but the harness itself simply isn't up to snuff.

Good solution but poor quality preamp connector

The receiver wiring harness for the power and non-preamp wiring was a perfect fit and had no issues. The major issue is the wiring harness for the preamp to the factory amp, it was almost impossible to line up the pins, after repeated attempts to line up the pins I almost gave up and hardwired it but gave it one more try using a very small pair of needle nose piers to line up the pins which did the trick. The issue is the pins are too loose and when plugging in the harness to the factory connector, the pins bend and actually cross connect into other pin slots creating a short in the connector. It takes a lot of patience, a magnifying glass and needle nose pliers to get the preamp connector to plug into the factory connector. The preamp connector needs to be updated to a more sturdy connector.

Not bad, not great

Main harnes was good worked as described. But major design issues with 8 prong speakerplug. Only one or two speakers would work at a time. The problem is the pins used are way too thin to make contact to the ford terminals. My solution was to rebuild the harness with larger pins which are big enough to make contact with ford harness. Yes it was a long process.

Main harness is great but the small black harness for the amp is garbage. It's basically just a plastic box with the connections loosely placed in there. Nothing keeps them in place so as you try to connect to the male end, the wires just pop out the back.

Metra 70-5510 Wire Harness

Bought this to use an aftermarket head unit to replace the factory MACH 460 in my Mustang. This harness is flimsy and it's difficult to line up the pins in order to push the clip in. Took me about 15 minutes to get it in, and the right front speaker has hardly any sound. You can only hear it if you put your ear up to it. All the other speakers work fine. I put the factory unit back in, and all the speakers work, so it's not the unit. Put the aftermarket back in, and that right front speaker same issue. Called Crutchfield tech support and the guy was stumped. We went through a bunch of stuff but he couldn't offer any advice. No matter how I line up the 4 RCA jacks, that one speaker will not work. I ordered another one hoping maybe I just received a faulty part. Still waiting for that to arrive.

Cheaply made harness..

Don't waste your time with the speaker adapter. The pins are not attached securely in the harness. It took 6-8 tries to get all the pins to line up and when they did, several never made contact with the female ends and each time a different speaker would not work. Cheap, Cheap, Cheap. Fortunately I have the skill set to cut all the wires and connect everything without the useless harness for the speakers. I opted to not hae a new one sent out because it would be the same and why waste a week of my time.

Very cheaply made but works

The wiring harness itself worked very well and was easy to install. The audio cables however are too cheaply made as the pins in the connector all wiggle around so much that it's almost impossible to get them to line up. Don't try to force it either, I did and one pin that failed to line up got pushed right out of the harness. Crutchfield happily sent me a new one which took several minutes of effort I to get the wiggly pins all lined up. It should have been a 10 min. install and instead it took over a week to complete. The replacement part I received? It was just as bad as the one I originally had.

The power adapter worked well. The speaker adapter on the other hand was a disaster. Plugging it in initially, right side and rear wouldn't work. No easy way to know if it was plugged in deeply enough, or even if the pins were correctly engaged. Ended up pulling pins out of adapter and installing into original plug individually. Insulated and secured with electrical tape. I had purchased from Crutchfield before and been very impressed with the adapters provided to make the job easier. I purchased this as a gift and the "ease" of installation was not there due to this plug. Very disappointing.

Cheaply made Metra 70-5510 Receiver Wiring Harness

Received this wiring harness as part of a gift of a new stereo. But the harness for the speakers is hard to connect to the factory connection. The pins are wobbly and don't line up making it almost impossible to go on. Even when I did finally get it to go on, the left rear speaker wouldn't always work. Apparently a short in metra wiring connector. All the speakers work fine when connected to the factory head unit. And if I wiggle the wires coming out of the metra harness I will get sound. Now I guess I'll have to wait another week before I can have a working stereo.

A little disappointed with this product. the power adapter side was just great, but the piece that adapts to the factory speaker wiring (which goes to factory amp) was not of very good quality. The 8 little pins in the adapter would not slide into the factory plug... when I tried to push it on, rather than slide into the receptacles, the pins themselves pushed backwards out of the adapter plug (the metra plug).

Almost Perfect

Easy to install and once you get it it works great. The 8 -pin plug could be manufactured better. I installed my head unit in about fifteen minutes but because the pins were so loose in the 8-pin it took about 2 hours to get plugged in so all the speakers were working. I kept having to try and push the pins back in using a toothpick. Finally got it, but what a hassle it was.

Would have gotten a full 5 stars but the 8 pin plug going to the Amplifier was not a simple "plug and play" type interface like I am used to with metra wire harnesses. Albeit some blame has to go to Ford for having some difficult connectors in the 97 Mustang GT. So to explain, the pins in the 8 pin connector do not line up perfectly and requires some patience to line everything up. On mine, one of the pins partially came out the back of the connector, I kept trying to push it back in, realign, and push the connectors together. Finally my son said, just leave that one out, push the connectors together, then push the pin back into its hole. Worked like a charm. The other side of the harness connector hooked up no problem.

Stereo adaptor works but adaptor needs work also.

Only replacing the factory AM/FM cassette unit with a NEW aftermarket AM/FM CD player with bluetooth while still using the factory Mach 460 amps. Installation instructions are easy to follow. The black RCA harness connector needs to be sized correctly. The pins are easy to push out and I had to use a small flathead screwdriver to push the pins back in after connecting the harness. Also, the black connector does not slide all the way in for the locking tab to engage. I used tie-wraps to hold them together. No issues with the power harness connector. Pins stayed in place and the locking tab engaged. Since this harness is for Fords using the factory Mach amps, it would have been nice that it had included a +12 to +5 Volt DC power convertor. The factory amps require a +5 volt DC signal to turn on and all aftermarket head units put out a +12 volt DC signal (Remote wire). The issues with the black connector and this kit being all you need to install (power convertor) is why I rated it at 3 stars. The wiring harness does work. I also ordered/installed a +12 to +5 volt dc power convertor to supply the correct voltage for the amp turn on circuit. NEW aftermarket head unit sounds good.

Everything worked eventually. The radio wiring harness was fine. No issues. The rca to factory amp harness is laughable. The pins are loose and don't line up properly. After hours of plugging and unplugging the harness repeatedly and using a flathead screwdriver to adjust the pins so they would line up properly with the factory harness, I finally got all channels to work. Probably would have been easier and less frusterating to splice into the factory wires. From other reviews, it seems like I'm not alone with this complaint.

Finished my Install

Great product to finish your aftermarket radio install. To ensure you are getting what you need, make sure you get at least 4 RCA inputs on your receiver. Otherwise you will need to get two adapters that take the four plugs into two. I had to go the adapter route due to the radio that came with the car. As others suggested I did have an issue with the plugs on the inside of the speaker plug coming out. BUT I ending up just pushing them back in as I plugged it in. It does cause some issues when trying to plug it in. You have ti wiggle it and move it around it attempt to not get them to push out, but you can just push them back in after. It is better for them to be this way rather than breaking!!

Works

This kit works. However when plugging in the RCA 's adaptor to the factory plug the 8 pins do not line up easily and the pins are subject to being pushed out of the adaptor. You must make sure the pins insert into the factory connectors.

First time using an install kit instead of hard-wiring in a radio. Much easier, I don't know why I never got one before. The plug for the speaker wires didn't match the plug on my truck but luckily I was able to use the one on the old radio.

Cheap Plug

Unfortunately I have gone through 2 of the Plugs that plug into the aftermarket radio's pre-amp outputs and I have had to rewire using my old plug to make it work. Cheap pins in the plug bend and pop out of the back of the plug. Main harness is perfect, no issues there. Crutchfield was great about replacing the defective plugs, but I had to wire it to an old plug to work properly.

Still missing sound

I installed this per the directions, but am still missing sound from drivers front speaker. I get nothing out of it, even when I adjust the radio so only that speaker is on. I don't know if there is a loose connection or just a bad connection since the pins didn't really want to line up with the factory harness.

Some of the wires don't add up to what's on bag and seems some are missing but it got the job done

Power connector harness was perfect and worked as intended. The other harness for interfacing with the factory amp was a disappointment though. As mentioned in other reviews, the pins were loose and popped out when trying to plug it in and overall it simply didn't work. I resolved the issue by throwing out the factory amp and struggling elbow deep inside the dash tapping into the speaker wiring harness that goes from the amp to the speakers. If you have the same issue as I did, a Google search should reveal the wire colors on the harness to allow you to do the same as I.

Wiring Harness

All of the male pins on the amp connector plug were loose! And when I did get it connected, the speakers popped in and out, had to go to the local audio store and get a replacement harness

Put in my Pioneer DEH-X7500HD into a Ford Explorer w/Outboard amp. Easy after I figured out Ford color code on the factory wiring. I just used small blue wire nuts. Everything was working in a flash!

Poor quality

Problem with adapter plug for speakers mating with factory plug. Initially had no sound from left speakers. Found pins pushed out of adapter connector but pushing them in did not help. Was sent another set of cables and had the same problem except I did get some sound out of the front left speaker but not at normal sound level. Must be a problem with the mating of adapter cable and the factory cable. After spending way too much time trying to get this to work I returned the car radio and cables for a refund.
