First off, regardless of what Amazon's results say, this DOES fit my 2006 Tundra double cab WITHOUT the JBL system. Apparently there's a lot of confusion with Toyota stereos, definitely for the first gen Tundras anyway. If you have a stock JBL system, or one with rear entertainment, or even one with rear headphone jacks, you also have an external stock amplifier. If you have an access cab you most likely have one no matter what stock radio it came with. On those radios there will be a single 20-pin plug that leads to the amp (behind stereo in reg cab, under rear seat in access cab, behind back seat of double cab), which has 10 and 6-pin plugs like this harness. You can bypass the amp by connecting this into the stock harness coming from it - but I can't say firsthand how well or if this even really works. Most people use the Metra TYTO-01 instead - Metra TYTO-01 JBL Amplifier Interface Harness . However, some have a non-jbl system with external amp (made by fujitsu ten) and it seems the TYTO-01 doesn't work with that one. At any rate, if you don't know what stock system you have, I'd HIGHLY suggest removing the radio before you order to confirm whether or not you have the jbl, etc 20-pin harness or the 10 and 6-pin harness like this one. I got lucky that my double cab only had the most basic stock radio and this is the correct harness for it. All the wires matched the new stereo's harness and it was a simple plug and play install.

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.

My wire harness came with connectors on both ends not just the factory harness end. Like a dummy though, I thought they sent me the wrong part since it wasn’t the one shown in the photo with bare wires to connect to an aftermarket stereo, then realized the end I cut off had a connector that would connect directly to an aftermarket stereo. All I had to do was disconnect the one on my Alpine and plug this one in. It also has other connectors in parallel to add more amps and speakers if you want to expand your System later. It didn’t come with the pinout but if you are connecting it to a universal stereo with the built in connector you don’t need it. I bought mine from warehouse deals. I suspect someone returned it because it wasn’t bare wires on one end like the photo which may also be why the pinout wasn’t included. Mine was for a 2005 Scion xB. Works perfect. Scion for some reason uses two harness connectors instead of just one. Two speaker channels on one harness and two on the other.

Easy connectors, plugs right in to existing wire harness

Super accurate plugged right into my vehicle great quality and functionality

Sometimes you open a radio bay and find out the factory made a midyear modification. It's a good idea to have all the installation aids you can. Being able to wire any which way you want is a lifesaver. Be prepared for the worst and hope for the best. It's nice when doing an install to be able to prep your needed wiring harness "on a workbench" and not while you are hanging upside down under a dashboard! I've spent a few hours laying backwards on a drivers or passenger seat with my feet dangling into the rear compartment. Staring up at the bottom of a dashboard while the brake pedal and accelerator grind into my ears! Too old for that excrement. I buy all the wire kits beforehand and that way I can solder and heat shrink in "comfort" and do a quality job. With room for all the schematics and needed tools to be right at hand! I may end up with spare harness parts, but I can do the install in one fell swoop and not wait for a needed part to be discovered on some dusty back shelf and shipped to me. It's nice to have a place to "bench test" the new head unit before plunking it into the dash. A couple of powered computer speakers can verify your unit is putting out to the RCA jacks a reasonable sound and not "cat howling. You will probably need 4 8 ohm test speakers to verify the high level output. A set of "alligator jumpers is nice to have for temporary test connections. It's a couple of extra bucks for doing a bench test, but it beats having to pull out a buggy new install. (And if it's your wife's car -- )

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.

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.
