hey bro go to cardomain.com and click on the store tab at the top...then in search type in Celica wiring harness and you should be able to find it...
It comes with a factory amp interface adaptor which you need to hook up an aftermarket head unit to u're stock speakers.
lemme know if you have any more questions
) but crutchfield should have it... or even your local bestbuy, etc..
