I'll give that a shot. I didn't want to fry anything. Thanks. According to the manual, my wiring is a little different. It shows a white wire going from the alternator straight to the regulator. In reality, it goes into a factory two wire plug with, I believe< a red/green wire. This white wire goes into the wiring harness towards the front of the cab. I haven't traced it out yet, I just tapped into it for the regulator. I hate not being able to drive the truck, and this is starting to drive me nuts....
