[FASTSUPRAMAN]

I am installing my stereo system and need a discription of the wires coming out of the factory head unit. I bought an adapter and it doesn't fit. My supra is a 97 TT. I am going to look tomorrow for another adapter but just in case I would like a description of the wires. The wires I am mainly concerned about are power, illumination, memory, and antenna. Please help!!!!

There should only be one harness coming out of the factory head unit. This harness will not be reused once you put an aftermarket head unit in. The harnesses you will need to use are located to the lower right inside the dash...at least they were on my 94TT. There will be two harnesses that you unplug which feed into the factory amp that is located below your passenger seat. Unplug the harnesses from inside the dash and plug your adaptor up to them. Everything should work fine.
