Finally something that worked!
I was pulling my hair out trying to replace the factory head unit in my 2003 Toyota 4Runner that came with the factory JBL audio system (amp and sub in trunk). I was minutes away from just driving my truck off a cliff out of frustration with how many different poorly documented factory wiring options there were for one freaking make/model of car. This was my 4th wiring harness I purchased and the only one that worked. It works perfect. Please note however the product does not match the picture in the description. There are no RCA cables at all, and the black box is a different shape see the attached picture. However, it seems to work fine by hooking up the eight wire leads instead of four RCA’s.I will explain what was wrong with the other three harnesses, as I figure people with the same vehicle as me may be running into the same issues and this is the answer.1st attempt – Metra 70-1761 – This is the standard Toyota 87+ wire harness, however if you have a JBL factory headunit these wires will not fit. This is for non JBL headunits, that only have 4 door speakers. I had to remove 6 panels and take my dash half apart to get to see these factory wires.2nd attempt – Metra 70-8113 – Fit one of the three factory JBL harnesses, and the new head unit powered on, however no sound. Found out part of my factory JBL system was an amp in the trunk that powers 10 speakers. This harness didn’t provide the necessary data signal to the amp to turn it on, so there was no sound. The blue “amp on” wire did not work.3rd attempt – Metra 70-8117 Amp Bypass Harness – Decided the bypass the amp and center/tweeters all together and just hook up the 4 door speakers with this bypass harness. It did not fit the factory harnesses, and with some extensive googling for wiring guides i found out the specific model factory headunit i had (JBL 56827) has three plugs on it, however none of these 40 some wires work for bypassing. They are all for audio-in expansions and steering control and other stuff. This is about where I lost it.4th attempt – This – It doesn’t look at all like the picture. There are no RCA connections as pictured, and the black box is completely different. My new headunit had RCA connections which made me think this was not going to work. I figured it was worth a shot though so I wired it up to the 8 F/R L/R speaker leads. IT WORKED! It was sounding a bit distorted so I tweaked the attenuator knob and now it sounds incredible and clear. There is about a 5 sec delay from turning my truck on and off till you hear any sound, however it seems to work consistently. There is no steering volume/track control for a JBL 56827, those wires are on a different harness slot that wasn’t part of this package.This is the most expensive solution of the four I tried, but it is the only one that actually worked, and the results sound great and functions perfectly. I lost steering wheel volume control, but it sounds like for another $50 you can get a universal steering wheel control adapter. However I’m pretty much over this project, and I’m fine with turning the volume knob by hand. It is so much better having a modern headunit in place of the crappy JBL factory unit, the audio sounds much cleaner and more full despite not doing anything to the factory speakers yet.

Works in 2007 RAV4 Limited Edition with JBL stereo.
After ruminating on whether I needed to continue to use this original amplifier with my new ATOTO head unit ( several people said they didn’t use the original amplifier with their new head units) I decided to try to preserve the functionality of my original amplifier. I did have to make some connections to the wire harness on my original amplifier but instructions were clear and stereo sounds good.

Easy install
Works great. A bit plug n play and some wiring. Pretty straightforward. Retains JBL system

Works for 05 Corolla
Took a lot of time to get it all wired together but instructions were straightforward. You must also look at your stereos wiring and make sure they correspond to each other. overall it works with factory JBL speakers system and sounds great. Price is a bit too steep in my opinion but if you are interested in aftermarket stereo this is works.

Excelent
I have a 2006 Toyota Rav4 with a JBL amplified system. I replaced the original radio and needed a harness for it. It was very frustrating trying to find one. After buying several and not getting them to work, I found this one. It’s really worth it. The connection is quite easy, and everything works wonderfully. I highly recommend it, and for the price, it’s worth it.

can’t recommend, poor audio quality. unreliable.
Where to begin, the gains adjustment never sounded right, this unit would constantly clip the signal from my alpine head unit. I verified clean signals from the head unit with several tools trying to troubleshoot the problem. even at the lowest gain setting, the output of this to my factory amp would clip. Even when it was not clipping the audio quality was terrible. The stock head unit sounded leagues better. In the end I would not recommend this, and instead would recommend 2 other options. 1.) bypass the amp and used the speaker outputs from the head unit directly. 2.) get a high quality aftermarket amp and rewire the car. I went with option 1 and my IS300 sounds amazing.

Not a Perfect Solution but It Works
Used it to install a double DIN aftermarket radio into my 2003 Lexus ES300, retaining the non Mark Levinson factory amplifier. Everything works fine except fade control does not work, this is a known problem with this adapter.Some people have been able to achieve a particular Fade front to back ratio by setting the fade on their factory radio before uninstalling it. The fade setting is retained in the factory Amp, at least until power loss from a dead battery.One other caveat I found which is not mentioned anywhere in the manual or on the internet are the two ground wires. One is system ground which is required, the other black ground wire is for the polarity of the illumination circuit. If your radio needs 12v+ for illumination or backlight, then connect both grounds to chassis ground. If your radio needs a (-) negative trigger for illumination, then simply leave this ground capped/taped/heat shrunk etc, not connected to anything.
