Sorry Guys, I should have known better. It's a 4.3 and a 4 dr Blazer. If it was a pickup I would pull the bed up in a heart beat, since with my condition I have a great cherry picker and an over head chain block in the garage.
The ground I saw broken must have been the filler static ground., braided copper. Since I really can't reach the module plug I'll probe the gray and black where I can reach it.
BTW this Blazer was the Girl friends and when she got a new car I told her to keep the blazer for the winter. As it turns out I have been using it most everyday and I'm starting to miss it already.
