My son has an 82 Blazer with a 6.2l diesel. He had an electrical fire a couple of weeks ago. Since then we have put in a new 18 circuit harness from Painless Wiring. They have been very good so far but do not know how to wire the Glow Plug control circuit. Is there anyone out there that has a wiring diagram that we could borrow / buy. Any info would be greatly appreciated as he is going off to school the first of October.
