About the Metra 70-8112 Receiver Wiring Harness

Metra 70-8112 Receiver Wiring Harness

This vehicle-specific wiring harness makes connections between your new car stereo and your car's electrical system.

Metra 70-8112 Receiver Wiring Harness

This vehicle-specific wiring harness makes connections between your new car stereo and your car's electrical system.

First, attach the color-coded wires on your Crutchfield-supplied harness to the wires from your new stereo. If you're not using a soldering iron, we recommend that you purchase some wire connectors to secure the connections. Check out our handy article on three ways to connect the wiring harness here.

Now, once this harness is connected to your new stereo, you'll be able to plug right into your car's factory radio connector. This harness saves installation time since you won't have to cut factory wires individually, and this also enables you to re-install the factory radio if needed. A detailed instruction sheet comes with the harness. Warranty: 60 days.

Installation Note: This harness uses your factory amplifier; your new stereo must have two pairs of preamp outputs to connect this harness.

Please read this important note: This harness may not contain provisions for every wire needed to complete your installation, and it will not accommodate special navigation, video, or factory steering wheel control connections. You will need a special adapter if you want your factory steering wheel audio controls to work with your new stereo.

I called in support and getting highly technical help on wiring up to the built-in the car amp that I couldn't believe that it worked perfectly. With this simple harness my old car now adapting the high tech android radio with wifi gadget.

Pros: Simplicity

Metra 70-8112 Receiver Wiring Harness

Crutchfield customer from White, GA on 12/30/2018

1999 Lexus ES300

Verified customer (What's this?)
Verified employee purchase (What's this?)

Good idea, that didn't work for me. The factory amp caused a constant high frequency whine at all times (not alternator noise) even with engine off. Needs a direct battery + feed and ignition feed and ground from a source "other" than the factory radio harness. Because, battery power, ignition voltage and ground all come "from" the factory amp. Also, the amp turn on wire from the aftermarket head unit must be wired to turn on the factory amp. So now you don't have a dedicated turn-on wire for your subwoofer amp. SO, I disconnected the factory amp. Made a speaker wire harness to plug into speaker output connector at the amp using the speaker level output from the aftermarket radio. With factory amp disconnected, you no longer have either of your power sources or ground to the radio since they came "from" the factory amp. So after all this, the Metra 70-8112 is totally useless for a Lexus/Toyota application. Save yourself a headache and just pre-make a harness and skip this one.

Pros: Good idea...

Cons: ...that doesn't work

Harness plugs right in to car. No illumination wire. Looked online to find which pin is illumination. Used a piece of 18 ga. thermostat wire stripped to pin length. Added a dab of silicone to secure, and now illumination circuit works fine.

Pros: Plugs right in

Metra 70-8112 Receiver Wiring Harness

Crutchfield customer from Scottsdale, AZ on 1/16/2018

1997 Toyota Land Cruiser

Verified customer (What's this?)
Verified employee purchase (What's this?)

Perfect fit to wire up my new head unit going into my 1997 Land Cruiser. It exactly matched the Toyota harness in the dash. The 4 finished plugs fit snugly into the back of the JVC KD-X340BTS I purchased. I called up Crutchfield tech support and was walked through matching the remaining wires to the JVC harness. Talking to tech support made it a piece of cake. Soldered them (because I'm old fashioned) and was done in 15 min. I also like the fact that this harness has the wire tips pre-cut so all you have to do is slide off the tip. I hate cutting wires and having a few copper strands come with the strip.

Cons:

I bought this piece so now I've been through 2 harnesses and Crutchfield told me this would fit my 1999 Toyota Avalon xls. Wouldn't work so then I cut one of aux cables like Crutchfield rep told me and still no result. I could see the screen but no sound which was my whole issue from the start. I wish u all would send me another now I'm working with 3 aux instead of 4

Pros:

Cons: Did not work

This harness was very easy to install, with one call to tech support with a question about one wiring problem which was rectified very quickly. Only disappointment is now I have alternator noise! Probably because of the common ground design (I think?). Otherwise, works fine.

Receiver Wiring Harness for 1998 Lexus ES 300

Peter from Henderson, NV on 5/23/2016

1998 Lexus ES300

Verified customer (What's this?)
Verified employee purchase (What's this?)

The METRA 70-8112 harness works just fine except that it does not have an Orange illumination wire; however, the harness DOES have the connector for a power antenna. It is the solid blue wire in pin 8. Since my car does not have a power antenna, I removed the pin 8 connector and reinserted it into the pin 2 position, and was able to connect the illumination control wire to my new radio. Also, the RCA connectors grounds are not separate form each other or the radio's ground. This caused a ground loop because of the way that the 1998 Lexus ES 300 sends power and ground to the receiver via the 5 channel amp behind the glove box. Grounding the radio directly to the frame did not fix the problem. The fix was to add a Monoprice 106909 Four Channel Ground Loop Isolator to the RCA outputs. Now it all works.

Pros: Works.

Cons: No Orange illumination control wire. Combines ground wires into one pin.

Why no illumination wire??

Jim from Duncan, SC on 2/29/2016

Verified employee purchase (What's this?)

Worked great except for missing the illumination pin and wire. I used it in a '95 Avalon, integrating the OEM amp. It is really annoying I had to rig up the illumination wire around the adapter connectors. Seems really silly it was left out.

Pros: It made the installation mostly easy.

Cons: Missing illumination pin and wire. I mean, why is that wire missing?

Very good

j from Maryland on 11/5/2015

1998 Toyota Avalon

Verified customer (What's this?)
Verified employee purchase (What's this?)

Very good. Worked well with JVC KD-R760 in 1998 Avalon, 7 speaker. Only thing missing is there is no connection to Illumination wire (pin 2) in Avalon harness. Don't know why they didn't include that. Without it, display won't dim when headlights are turned on. However, it was easy to add a jumper to go from the pin 2 wire in the Avalon harness and go to the JVC Illumination wire. After doing that, the display dims as it should. Otherwise, it was fine, seems well made, and worked well.

Cons:

This wiring harness lacks the illumination wire, which annoyed me as my aftermarket stereo supports automatic dimming. I ended up replacing this with a different wiring harness since that one does have the orange/white illumination wire.

Integrate factory amp

Crutchfield customer from California on 10/6/2015

1995 Toyota Celica GT

Verified customer (What's this?)
Verified employee purchase (What's this?)

I ended up using an aftermarket amp in my car so I never used this harness. Keep in mind that this is intended to wire up to your existing factory amp. If you wanna run you're own amp or run the power from the head unit, be sure to pick up the other Toyota harness Crutchfield offers. I'd image it would work great if you had other plans. Good quality!

Pros: Can integrate factory amp

Cons: Will use up for 2 pre-amp outputs so only use if you don't wanna add a sub in the future

So this is my 3rd harness I have received from Crutchfield. I called the number provided on your Web site to insure I was buying the correct part. When I tried to explain my situation your representative was pushy and would not let me get a word out. He promised this was the correct harness. It was not. So thank you Crutchfield for wasting more of my time and money.

Pros: Shipping was fast

Cons: Not the correct part

Crutchfield response on 10/7/2014
Sorry about the trouble on this purchase. However, we want to let you know that as a result of your information we have removed the harness from listing as working with your vehicle, and we have refunded the cost of the harness to you. We are in the process of looking for a supplier of a harness that will work for this application.

So..wiring a stereo in some of these cars nowadays is lot different then when I was younger. My son's Toyota comes with a built in amp and and a trunk mount cd changer. Wiriing was going all over the place to say the least and if you try to get to the wiring before it begins its journey behind the dash, you have about an inch to work with in a very tight space. The wire colors mean NOTHING....you need a special legend to get the right ones - and then those are the ones going into the amp - not the radio. So - called Crutchfield - WOW - they knew EXACTLY what they were talking about. I ordered this harness to plug into the existing radio harness and it WORKS GREAT!!! No splicing, no issues... If I had purchased this first, I could have save about 3 hrs pulling off the glovebox, reseraching wiring diagrams, watching youtube videos, puttung things back on the car.... Thanks to the Crutchfield folks!!! You guys were awesome. Really love the tech.support!!

Pros: Easy, easy, easy

This was the harness Crutchfield sent to fit a 97 Celica with 6 speaker system and aux amp. It is NOT the correct harness for that application. I made it work by cutting off some ends and re-wiring. It was better than nothing...but not by much

Verified employee purchase (What's this?)

This harness was easy to connect and all's well ends well right? Wrong! Once you turn on the radio you get this annoying buzzing sound that can really be irritating at times. Keep in mind this harness went on a sc300 1998 with full trim package and everything. I have this can be aliminated by installing an aftermarket amp and speakers. Also if you have a center subwoofer you will lose it. So to the chase...easy harness to hook up and install but annoying sound once radio is on.

Pros: Easy to install

Cons: Annoying buzzing sound

Verified employee purchase (What's this?)

Worked like a charm! Easy to install following the head unit and wiring diagram provided with the harness. Allowed me to continue to use the factory amp in my '98 Avalon and the sound from the new head unit is very good! I used solder and heat shrink to join the head unit to the harness... very easy to do, but if you prefer not to solder, you could easily use wire connectors to do the job.

Pros: Fit perfectly. Low Cost Works as advertised

Cons: Wish the illumination wire was part of the harness as an option.

This adapter made for the easiest installation I have ever done, and it works great. I have installed a lot of car radios, most from Crutchfield, and this adapter made this installation the easiest ever.

Pros: Almost plug and play. Only a few crimps and no cutting of the harness in the vehicle.

Wiring harness for 1999 Toyota Avalon

Paul from Port St. Lucie, FL on 3/28/2012

1999 Toyota Avalon

Verified customer (What's this?)
Verified employee purchase (What's this?)

Unfortunately, this wiring harness did not fit my Toyota. Since I had the front dash of the car already taken apart, I got a replacement harness from a local dealer and had to splice all of the wires together. The necessary wiring harness would have required 2 concentrators, not 1. Neither of the Toyota concentrators matched this wiring harness' concentrator.

Pros:

Cons: It did not work with, or match the wiring in my 1999 Toyota Avalon.

Came along with the Clarion radio for my 95 lexus es 300. Had everything good in it but there is no connection for the illumination control. So I couldnt set up the illumination control in the radio which goes dim while you turn on the headlight. I checked the harness several time but it doesnt give me the provision or mark sheet doesnt show me where to connect. Otherwise everything is perfect.

As a previous reviewer pointed out, this harness is missing the ORANGE ILLUMINATION lead in the number 2 position. If you are OK with not having your radio dim when you turn on your headlights this won't be a problem. I want the radio to dim when the headlights are turned on, just like the rest of the interior lights. Sure wish I had read the previous review ahead of time. I called Crutchfield to ask what could be done to fix the harness and they said sorry, they don't make the harnesses and there is nothing they can do for me.

PROS: Very good Quality. Fits just like OEM conector on Radio, with a nice positive feel. Secure. (Good job sourcing this Crutchfield!) Wire colors matched radio for easy matching and connection. CONS: The connector is MISSING a wire in the #2 position for ILLUMINATION. (usually an ORANGE wire) If your car does not have a 12v wire for illumination and/ or you don't care about dimming your radio lights with the headlight switch on the car, then this may not matter. Crutchfield was VERY accomodating and was able to help me and sent me a second one to take a wire out of to use. It required me to basically destroy the connector, and I carefully reused the crimp connector and soldered an ORANGE wire in place. The result looks like it was made that way. I have years of experience with this type of work and access to the proper tools. I only rate this 3 stars because of the work required for my application. I would give it 3.5 stars if I could. If the orange wire was there, I would have gave it a 5 star rating. In case this info helps: My car is a 1995 TOYOTA CELICA GT with 6 speakers, double din headunit with separate amp. I installed a Kenwood DNX5120.

Product Research

Features

Metra Wiring Harness: Metra wiring harnesses prevent you from having to cut your vehicle's factory radio plug when replacing your factory radio with an aftermarket head unit. Simply solder or crimp the Metra wiring harness to your aftermarket head unit's harness (solder & crimps not included), plug the aftermarket head unit's plug into the rear chassis of the aftermarket head unit, and plug the Metra wiring harness into your vehicle's factory radio plug.

Note: Installation tools, hardware, & accessories are not included & sold separately. Please see the Accessories tab for recommendations & availability.

Wiring Notes: If the Metra wiring harness is not equipped with a ground wire, you will need to ground the aftermarket head unit's ground wire to the metal chassis of your vehicle. Some vehicle's may require you to bypass the vehicle's factory amplifier (in another location from factory radio) or hardwire certain connections. If your vehicle is equipped with factory steering wheel controls, an additional adapter is required & sold separately.

I see this and most are designed with only 4 speakers, What about the 7 speaker factory system.? Avalon Toyota 98 - Wire Harness???

This one actually runs to the factory amplifier and supports the premium sound system in your Avalon. It should work perfectly. I had the same concerns about my 97 and it works great. Hope this helps
[ Joseph Allen  Dec 13, 2018 ]

This harness is used to install a new radio into a '98 Avalon that has 7 speakers in it. There is an amp in the vehicle that powers the speakers and get 4 channel preamp audio from the radio. The RCA connections on this harness is meant to plug into front and rear preamp outputs on the new radio My Bio: https://www.crutchfield.com/bio/Paul

I have the same 7 speaker system on the 98 XLS. I have not yet upgraded my Avalon, even though I purchased everything to do it in Feb. 2017. This is my take on that, even though I have not looked at the wire harness my assumption is that the Front Door Tweeters split off from the bottom speakers and that the Back Bass Speaker on the back shelf running under the center brake light is a "Phantom" Speaker running from the Rear Door Speakers via their wiring harness. This design was used years ago. I do have the Electrical Workshop Manual and will try to see if I am even close on all this. Things move at the speed of Bob and I have been addressing the Speedo issue as both the Avalon and Lexus models have an electrical bridge that cause it to fail intermittently or permanently. Good luck with it all. I will try to update this later when I have more... BobD.

I have a 99 Toyota Camry le and I have an aftermarket head unit and a factory amp that I would like to use again like when it was factory , ur website says that it won't work for me but sonicelectronix,com has the same harness and their site says that it is compatible. I would really like to know if it will work or not??

Thanks for your question. For information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system.

Q
I have a sony HU with only one set of outputs. Is there a connector I can get that will fit with this idea?
[ Jason  Apr 21, 2014 ]
1 answer
A
I forwarded your question to an Advisor and they responded with the following: He'll need a receiver with a 4 channel pre-amp output to use that harness. The RCA connections go to the factory amp and each RCA connection represents a speaker. If he doesn't connect two then he won't be able to use those speakers. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat.
