    I'll be doing mine maybe this weekend.

    If you look at the connector VERY closely, you can see these numbers.

    pin 9 Ground

    pin 1 constant +12V (fuse #8 for clock and memory)

    pin 2Switched +12V (fuse #1 from ignition switch)

    pin 3 power antenna ( you probably don't have one)

    pin 4 Left speaker +

    pin 7 Left speaker -

    pin 5 right speaker +

    pin 6 right speaker -

    seperate brown wire is for reostat

    seperate yellow wire is for dimmer

    If you are in the electronics field or maybe Radio Shack can help. The mate to the connector is an AMP#1-480673-0

      There's some useful car audio and general wiring info at: the12volts.com

      I recently installed an Aiwa unit in my 86 240 - made easier by the fact that the previous installer had figured out the matches between the non-standard Volvo wiring color-code and the wiring color scheme that all maunfacturers seem to use these days.

      When I first turned up the volume the head unit shut down. Found out that the previous Technics cassette player had a 1 amp in-line fuse on the yellow wire now used for constant 12 volts. New Aiwa unit has a little transformer and some electronics in an in-line box with a 10 amp fuse on this same line. 1 amp fuse had to go.

    Gene I don't have your answer but my 1990 240 wagon B230F with the original volvo radio cut on and off I just bought it from an a friend who said it had a short in the speakers. Why are you changing your radio possibibly for the same reason?

    Hello,

    In my experience the volvo radio wiring is a fairly straight foward deal.

    As most radios are. You need ground and two hot wire. And of course the speaker wires.

    One of the hot wires is only hot when the ignition is on, the other(for your presets)is always hot. Use your volt/ohm meter to determine which is which. For the speaker wires, use a 9v battery, placing one wire to + the other to -, when its right you will see the speaker cone move foward, that identifies the positive and negative side of the speakers. This is what works for me.

    Hope this helps.
