Just purchased a 77 Cobra II and someone was playing around and the ignition switch won't start the car. I replaced the ICM and Volt reg and if the ignition is in run position i can short the silonoid and car will run and start no problem. I'm trying to trace down the fault but need some wiring diagrams and I can not find anything online and have ordered a manual but it's going to take 3 weeks to get to me.. any help so i can get started on my rebuild.
