I found out that the wire going from the glow plug controller to the #8 plug was bad. I replaced it with some wire I had. I'm figuring that the other wires probably aren't far behind, though. Those of you that have replaced the wiring harness:
- Did you buy an actual "harness" from GM ($80 plus $30 for the two quick-connects for #'s 4 & 6), or just get fusible link wire from some place like NAPA? What gauge wire? (can't read it on my wires)
- What about those metal tubes for #4 & 6? What is that for? How do you remove them? Any problems if I shorten them? The tube around #6 comes very close to the downpipe.
- Why does soot gather on the plugs on the passenger side?

I know, alot of questions! [img]tongue.gif[/img]
