Anyone have a wiring diagram for the wire connectors for the oem radio?? I am trying to install new afermarket radio and the FAQ doesnt have the detail. I know I have to bypass the amp but I would like to know the various identities of all the wires. tx db

    Wiring colors differ over the years. I have wire colors for 86 and 89's.
    Also have pinouts for the amp, if you want to try powering that.
    I tried that but it turns out the the wire which activates the amp must be shielded or it acts as an antenna for ignition noise (ie it worked fine when the car was not running).
    I decided to remove the amp and use the built in amps of the radio, which as it tunrned out, were better the Volvo amp.

      As mine is an 89 745tic then I could use the Wiring ids. I will not use the onboard amp and stick to the radio amp. Please send what you have to david.crilly@aero.org tx db
