Thank you so very much. The dealer couldn’t even give me straight answer on the wire codes for my 94 celica. I probably could have figured it out but your site made things sooooooooo much easier and faster. I can not thank you enough.
Jeremy, we’re glad we could help you with your car radio wiring diagram needs.
On my 1994 Toyota Camry LE’s stereo I noticed a round connector (left site looking at the back of the stereo). Can I somehow use the R IN and L IN connectors in that round connector to get a Line In through my stereo? Thanks.
Mike, the round connector is used for a factory cd changer. As far as we know, you can’t splice into the cd changer plug to make a standard line-in. Hope this helps. Good luck.
you guys helped me so much!
