It's all Black Magic. I used to work on the radar on F4-J Phantoms when in the service and learned a few things. What I don't get is why you would all of a sudden need to to start rewiring your car when it had been functioning. If you have a broken wire, isolate it and fix it, put your Canbus compatible bulbs in correctly and "VOILA", everything should work. I sometimes think we make some simple things more difficult than they need to be.
