As you know the wiring harnesses in the 82-87s are particularly susceptible to crumbling. I am told that Volvo recognized this and produced a newer set of three harnesses (drivers side, engine, and passenger side). You can tell them in that they have a darker grey block connector in the engine compartment. I found the last one that Volvo had in the U.S. for the driver's side and bought it -- ouch! I have looked high and low for both the engine harness and the passenger side harness. We found and installed a used engine harness. We still need the passenger side harness. It starts with the computer connector in the passenger compartment and runs through the firewall and out along the passenger side of the engine compartment out to and includes the lights, air mass sensor, and windshield washer motor. It also has a branch of the harness that runs across the firewall (on the engine side) with three wires that attaches to what I believe is the cruise control component.

I have asked Volvo to do a nationwide search after looking in their warehouses and they have come up with "gee we don't know where to look --sorry".

I have one contact in Seattle (where we bought the upgraded engine harness). While his prices are sort of reasonable he is not certain that he has one and I would have to drive another seven hours (round trip) on the chance that we may be able to find one and maybe not.

Oh yes, the part number for the passenger-side harness that I am trying to replace is: T-1324973-2. Driver's side that I've replaced was T-1324972-3.

Hope that is enough clues. Any leads or suggestions?
