Truth be told Nailhead, anything electrical scares me. Just the words wire harness scares me. I fully understand what you mean when you say 12v over the counter items are easier though. I'm kind of a fully stock original kinda guy. With all my recent trouble with my coil problem, I'm happy to report that the last two times my truck was out on the road, she ran perfect, including tonight. I'm really impressed with the Pertronic's electronic ignition system I installed. Seems to be smoother through the rpm range.
