im replacing my cd player in my 1994 acura integra, the current cd player i have in the car is the type that the whole cd player comes out of the vehicle ( no detachable face ) so im a little confused as when i took out this cd player i didn't see any type of wiring, just a jack on the left side where it looks like it plugs in, now do the 1994 integra have a wiring harness or do the cd players just plug in i guess you can say.
