For anyone trying this, more information. I found the end of the conduit. It is located under the air cleaner box (Turbo model - had to remove the air cleaner box) clipped to one of the brake lines. I found that if I pushed the wire in from the drivers compartment end, and had an assistant hold the conduit as straight as possible (after unclipping it from the brake line, removing the holding clip and pulling the rubber end off) it was possible to push the wire thru. Once thru it was a simple matter of routing the wire to the battery and from the drivers compartment back to the rear of the car. Then all that was left was to reassemble all the pieces removed in order to gain access. It is no wonder that the Volvo dealer charges an arm and a leg to do this. Even after you figure out how to remove everything, it takes a while. I would guess that if you already knew how to do this, it would still take two to three hours to completely hook up the harness.
