Well wish me luck, I stopped by advanced auto they said online they had one in stock picked up the coil. Used an old thread from 86MAX on the wiring diagram. Truck fired right up. I do have one left over black wire that has a female spade that went to ballast that I am not sure what it does. But truck is running fine with no ballast wired as the old thread said. Sure hope it doesn’t take a shit in 5 months.
