Fits as advertised
Worked perfect with my 08 Toyota Highlander. Everything plugged straight in and was easy to connect.

Fit right in, was easy to install. Works great!
My 1994 Camry had a factory cassette/CD player when I bought it last year. I was afraid to put a cassette into a stereo that old, and the CD player worked but hey, only 1 CD at a time. There are some pretty nice car audio systems available and I got a cheap one that handles bluetooth on the phone, SD cards, USB sticks, etc. The installation was a walk in the park! I popped off the bezel, removed four screws, and the old system was out. The new one had wires hanging out and the colors on this harness matched perfectly. It took about ten minutes to crimp those wires and then the two connectors plugged right in where the factory unit was. I plugged in the antenna and screwed in the four screws, then did a smoke test before putting the bezel back on. No smoke, just music :) It doesn't get much easier than this. If I ever decide to get a fancier stereo later, you can be sure I'll be back for another one of the harnesses.

It works.
It's wires and plastic, and it works like you'd expect. Also, and I can't guarantee it, this was made easier to use by the head unit I bought to use it with. The harness for it was pre-stripped. You could literally just pull off the plastic ends of those and crimp this down on them and be done. I wasn't expecting it and ended up stripping 3-4 wires off it before noticing. I hope yours does that too.

Works Great!
Used this to fit an aftermarket stereo in my "2012 Toyota Prius C" after the stock one stopped connecting to Bluetooth. Everything was pretty much plug-and-play. I would recommend using a decent crimper as the $10 one from Walmart made the connections feel iffy. Still, after hours of listening, the connection is solid and I have had zero issues!

Fits 2005 Camry with JBL without Nav
At first I thought I bought the wrong harness for a 2005 Camry XLE JBL without Nav. I put everything together then tried to put it in the car and it wasn't even close to fitting. The issue is that you don't want to plug this into original stereo plugs, but to the jacks physically located under them. There will be a white and blue jack, these go to the amplifier. Unplug these and plug the Scosche in, leave original stereo plugs hanging. This results in the stereo powering the speakers but you will notice zero difference (actually sounds better IMO). I combo'd this with an ASWC-1 and Metra 70-8114 and have all controls from the steering wheel working fine. Recommend Wire Harness Tape to clean things up. All wires went to same color, no need to break into wiring or cut anything, just take time and pull up instructions for all parts.

Works with 2012 Sienna LE and Power Acoustik CPAA-70M Double DIN Receiver
I recently replaced the stock head unit in a 2012 Toyota Sienna LE with a Power Acoustik CPAA-70M double DIN receiver. The wire colors on the Power Acoustik unit agree with those in this wire harness. This combined with the butt connectors made installation quick and easy. The Sienna did not have the upgraded audio system with the JBL amplifier. Note that his wire harness kit does not include a kit for the Sienna's steering wheel controls, but it was easy enough to find a wiring diagram and make small splices into those wires. The SWC wires on this Sienna were in the 20-pin harness that must be unplugged from the stock head unit during removal. There were three wires grouped consecutively along the top row, left side if looking at the plug from the rear, where the cables enter the adapter. SW1 was black (B), SW2 was light green (LG), and SWG was sky blue (SB). SW1 handles the seek and volume buttons while SW2 handles the rest.

The colors don't have to match the vehicle wiring!
When I installed my Pioneer double DIN unit in my 2000 4Runner last week, I followed the advice of the various YouTube videos and removed the Toyota amp below and behind the original Toyota unit. The two plugs that connect to the rear of the amp are the ones that the Scosche harness connects to. What the videos don't tell you is that the Scosche wiring colors will not match the vehicle wiring. For example, the black ground wire becomes a brown wire. In my case, I have a Toyota wiring diagram that shows the colors. Everything matches, even though the colors are all different. So don't freak out if you see the dash wires are different colors. Get a Toyota wiring diagram for your vehicle and check them. By the way Scosche was no help with this. They wanted me to use the old Toyota amp and buy a unit that could tune the feedback from the two amps, one in the pioneer unit and the old Toyota unit. Wrong. Just check a Toyota wiring diagram that shows the colors and rely on that.

Worked to install Pioneer FH-S520BT in my 2005 Camry LE
I attached it to the harness that came with my new headpiece. All wire colors matched. The attached connectors made it easier. My new stereo works perfectly.
