I've followed the threads concerning the wiring harness issue. I've never heard of the wiring harness being sold on eBay, or anybody using one from a wreck (you'd be replacing junk with junk).

I see you have a new headgsket. Your story is typical. This job requires lots of manhandling of the wiring harness. This manhandling probably spalled lots of insulation off the wiring. Open up part of the wiring harness and take a look -- you'll be appalled! Personally, I don't think it's worth looking for the individual fault. Even if you find it, you have a wiring harness with brittle insulation throughout. More problems are sure to follow.

What Chuck wrote should weigh in heavily. A bad wiring harness with future shorts can take out some expensive equipment.
