I'm installing an aftermarket head unit in my 88 240 because the radio sucks with the stock head unit. Here's the wiring description for the Volvo wiring:

Orange/white stripe: +12v
Black/White: Ground
Red: Left/Rear speaker+
White: Left/Front speaker+
Yellow: Right/Rear speaker+
Blue: Right/Front speaker+
Black: Speakers-
Green/White: Clock

OK. On my after market head unit, there is one negative wire for each speaker. As opposed to just one speaker negative wire on the volvo harness. How do I connect those wires? Also, on the aftermarket, there is a +12v Memory wire, is that the clock? I'm assuming it is. Thanks for any help you can offer!

Matthew

Why not just stop by a local electronics shop and buy the adapter for like $15.00.

Then that will eliminate all the problems.


BTW:The memory wire is for the clock and to keep all your stations.

Thanks. I think I'll just go the adapter route.

Keep me posted!!

Will do..........

I didn't notice the signature image option until earlier.

if a remember correctly you cant just buy a wire harness. volvo is a very odd car to do this kind of stuff with. there is am amp that you have to by pass befor the head unit will work. unfortunantly i have never wanted to F*** with the volvo like that so i have always had the guys install it for me. sorry i couldnt be of more help

Hey Matt, how were you able to get this to work? I'm having the same problem. I purchased this adaptor (http://www.scosche.com/scosche_caraudio.aspx?CategoryID=78&ItemID=VO00B) from Scosche, but the wiring doesn't line up at all. So I pulled the leads out of the plastic head so I could stick 'em where I *thought* they belonged, but still no luck.

Here's the Scosche factory adaptor:

And here's how the wiring in my factory harness looks:

I've tried every which way to put them together, with no luck. Any pointers?

Incidentally, what / where is this mysterious amp that may be causing me trouble?
