I'm not at the radio right now, however it was the stock radio that comes in the 1986 Volvo 740 Turbo. I replaced it with an aftermarket, somebody broke in my car and stole the aftermarket and the adapter, so I went to a junkyard and bought a Volvo cassette radio that was in a 1991. It's a nicer radio, a different model (obviously) than the original in my 1986. I found the wiring diagram for the new (junkyard) cassette radio, but need the wiring diagram for the 1986 so that I can either splice, or get a retrofit kit or something from Volvo (last resort). Any help greatly appreciated.
