Review on Scosche TA02B: Color Coded Wire Harness for Installing Aftermarket Stereo in Toyota Vehicles (1984-2017) by Jason Cho

My wiring harness had plugs on both ends, not just the factory end of the wiring harness. Although as a dummy I thought they had sent me the wrong part as it wasn't shown in the photo with the wires exposed for connection to the secondary stereo, I realized that the end I had cut off had a connector, which could be plugged directly into the secondary stereo. I just had to unplug one on my Alpine and plug this one in. It also has other parallel jacks to add more amps and speakers if you decide to expand your system later. It didn't have a pinout, but if you're going to connect it to an all-in-one stereo with a built-in jack, you don't need it. I bought mine from Warehouse Deals. I suspect someone returned it because there were no exposed wires on one end like in the photo, which could also be why the pinout wasn't included. Mine was for a 2005 Scion xB. Works perfect. Scion uses two harness connectors instead of one for some reason. Two speaker channels on one harness and two on the other.
