Ive got an 82 diesel blazer, and NOTHING works!!! The previous owner screwed up the electrical so badly that the courtesy lights wouldn't work if you ran 40,000 volts through them. First of all, the glow plug relay is new, so is the ignition switch and the starter. None of the shop manuals tells me which color wire is the "always hot" wire to the ignition. Whatever color it is, this vechicle does not have it. I think I got the starter wired up right, but Im not sure. I can't tell what needs to go where because the ignition seems not to work either (something to do with the missing "hot" wire???) so far, the only thing that works is the glow plug relay when I jump it directly to the positive terminal on the battery. Can anyone help tell me how I need to wire the ignition to get the thing running??? I think the most important thing is the hot wire running to the ignition, but how the heck can I tell???
