Great! But..

Great harness for my Kenwood single din in my sc400. While it technically works as it should, i feel the kit should include something to correct the notorious aftermarket HU sc300/400 alternator whine. Knowing that this may be an issue during my install, I installed ground loop isolators but still to no avail- whine still there. Other than that though, straight forward, easy install.

Do not buy for 96-97 Lexus LX450.

Do not buy this for your 96-97 LX450. You need to bypass your OEM amp and this does not allow you to do that. If you use this adapter and install a new stereo head unit in also, you will get a terrible whining feedback noise whenever the engine is running. It is coming from your alternator. You need to bypass the OEM amp. Use the 'Metra 70-1761 Radio Wiring Harness For Toyota 87-Up Power 4 Speaker' instead and create your own wiring harness. Bypass the OEM amp. You will not regret it. Do not take everything apart twice like me and learn from my mistakes.

Its okay I guess

94 Lexus SC400, Pioneer system w/cd changer Easy way to connect the power and accessory wires. The ground wire works too but I elected to ground my new head unit directly to the trans tunnel. Amp turn on wire did not work. RCAs for speakers did not work, had to run my own wires to the trunk, bypass the stock amp and tap into the speaker outputs.

I used this harness to install the Kenwood KMM-BT728HD into my aging 1995 Lexus ES300. It works fine, however, i had to align the pins from the connector. In fact, i think the connector itself is a little on the cheap side. But.. it works...

4th time's the charm..

I literally had to buy 3 useless harnesses from different online retailers before finally getting this one... I was starting to think one that worked didn't actually exist and I'd have to go around my car's factory amp, but this harness works as advertised. thanks :)

Deck performance.

Works great with the deck as suggested. Only issues is that RCA connections gives off a hummm feedback, which is not at fault since it is a correct connection to the deck to factory amp of the Lexus es300. Best result and correction would be to omit the RCA connections and do a separate connection for highes and mids of the vehicle and get an extra amp to connect the separates and mid ranges for the vehicle, which will omit the humming from the deck itself.

Metra 70-8112 Receiver Wiring Harness

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.

Metra 70-8112 Receiver Wiring Harness

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.

Receiver Wiring Harness for 1998 Lexus ES 300

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.

Why no illumination wire??

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.

Very good

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.

Lacks illumination wire

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

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!

Awesome!

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!!

So so harness

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.

Wiring harness for 1999 Toyota Avalon

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.
