I was given a Volvo radio which was 'suppose' to fit our 1984 240. It is a TD-3141 Radio. It came with 2 amplifiers, and HA-3121 and an HA-3141. The main connector on the radio will plug right in to the harness in the car. However on our '84 the front speakers are wired in to the connector with the harness and the rear speakers have a 4 pin connector. The amplifiers each have a 9 pin connector. The HA-3121 uses 6 of the pins, and the HA-3141 uses 5 of the pins. I'm guessing that on the HA-3121 the yellow is the power and the black is the ground and the other 4 are the speakers. On the HA-3141 it looks like there are 4 speaker wires and a ground wire in the harness? There is an external yellow cable that is heavy on the 3141, is this the power feed? On the radio (TD-3141) there is also a yellow fused line that is not in the connector it has been cut, does this go to the yellow wires for the amps or where? Then there is the orange/black pair on a seperate connector what is this for? Also is the top DIN style connector front or rear?

If anyone knows the color code for the extra wires and/or the pinouts for the connectors it would be greatly appreciated.

Thanks!
