    Hi Guys
    Recently bought a 1990 740 (Base model) without radio/cassette. So I
    bought an original CR-702 off ebay figuring I could plug it right into
    the electrical connections in the car.
    HOWEVER, the previous owner must have wired in a non-Volvo radio and
    speakers because I can see non-standard (afterfit) wires which they had
    wired into the original Volvo connection block coming out of the car's
    dashboard.
    So, I can plug the stereo into the 10 pin connection box coming out of
    the dashboard and the sterop comes on OK -but I get no sound. I know
    the speakers work because I tried them with a portable radio.

    So, I can't figure out which wires are the speaker output wires from
    the unit. Can anyone help? The wires coming out of the back of the
    stereo are:

    Going to a black connection box with 10 pins:
    Red with thin white line
    Grey and thin red line
    Blue
    1 black one thicker than all the others
    Yellow with thin black line
    Yellow with thin white line
    green with thin brown line
    3 blacks with red rings, one of which goes to a separate 2 point
    connector
    2 reds with black rings, one of which goes to the separate 2 point
    connector

    The other confusing thing is there is a DIN male plug coming out of the
    car innards which I understand is used to take output from the radio to
    an extra amplifier of graphic equaliser. But the car does not have
    these nor do I think it ever had them.

    If anyone can help, I'd really appreciate it. I am trying to get the
    740 back to original spec and don't want to wire in a non-Volvo unit if
    I can help it.
    Thanks in advance.
    Pete
