I have searched quite extensivley on-line for wiring digrams for my 90 t-bird but, if i find any they do not match the ones in my car. I am in need of any info anyone has. The list on this site also does not match what is in my car. I have a stock cassette player, if that helps at all. PLEASE HELP!!!!!!!!!!!!

hmm...I would have recomended a wire harness but I see its too late for that. Was there a factory HU in there? With those wires twisted like that it looks like an installer did it. Might not be factory wires at all. ------------- Nik

Yes there was a factory HU in the vehicle. I don't know if there was ever any work done on the wiring but I can't seem to find a correct match. I really do not want to spen $150 on having someone install this.........UGH with utter frustration.

ok, Heres my guess, check it with a meter. Twisted wires are speakers, red is +12, black is -, yellow and orange, one is acc and one is ill. That blue wire might be a power ant. or amp. Again this is nothing but a guess do not hook it up this way without checking the wires. Thats just the colors I would have used if I had wired it. It really does look to me like someone re-wired it though. Check it with a meter and if you need more help we're right here. ------------- Nik

new problem?? Started multimetering the wires and the red or what i assume to be power is not reading anything. I have replaced any fuses such as the mem(5) under the hood, radio(15), and Acc(10). Is there anything that icould be missing. Please help.
