The Volvo4 radio cassette died in my 83 240GLE and I need to replace it.
The radio (Model RX-3AQ) has a 9 pin straight connector on the back. Does
any one have any idea which wire goes where? Power is ok as it is fused but
the rest....... HELP!

Cheers,

Paul
 
will get back to you when I've looked at notes in my manual. I had to get an
adaptor and rewire the non-standard Volvo wires on my 440. Have you got 9
wires. Methinks that I only had about 4 or 5 to match up when I did my
radio.
 
Affirmative. 9 wires in the socket, another to earth and the antenna
connector.

I guess 1 for power, one each (4) to speakers, one speaker earth, one
accesory and one is labelled dimmer..... I guess that dims the display. And
a spare. Remote for antenna motor? Trouble is, which is which. I will
get there.

This is from a post on the Brickboard www.brickboard.com that I copied and
used installing my stereo:

The year would be helpful.
If you are talking light green it is constant positive. It usually goes to
the trunk light too. Red is for the up signal from the radio.
Brown is the dash rheostat for panel lights
yellow is a dim signal to dim displays (your new sterio probably can't use
this)
green at the radio is constant positive
blue or yellow/black is switched positive
black is ground.
yellow/white and yellow/grey are front speaker positive leads
white and grey are front speaker negative leads.
red is the power antenna lead.
Depending on year there can be variations on this. You should always verify
leads with a voltmeter. Unless you have owned the car from new you don't
know if anyone has already messed with the harness.

Good luck,
