Help! How do I get this to work?

[Ace2424]

I have a 1994 Toyota Celica GT and I can't seem to get the radio that I used to have plugged into my Camry to work with the cars wire harness in the Celica.
All the places I look have the same wire harness that I do for Toyota. The problem is that the oem radio in the car has a plug that won't plug into the aftermarket head unit plug adapter. The oem radio in he car also says that it is one of the security types that will not work in any other vehicle. Does that have anything to do with it?
How do I get my Sony headunit to work with his car?

You should have 2 different harness, the stock Toyota that has 2 sets of plugs for power and speakers, then a 3rd plug (security)that does power/speakers and all in 1 plug, I think you're talking about the security plug that some toyota radios had. If you don't have the stock 2 plug set in the car but only the security 1 plug harness then you will have to trace wires off the security plug and hook them up one by one to your Sony deck.

Follow the wires and you'll find another one that will plug into aftermarket one. It maybe covered in tapes.
