I wasn't sure if anyone had seen this yet. There was an article in the latest Rod & Custom. Looks very interesting. It uses a LIN line to the control module in the front and rear of the vehicle. This means you can wire the whole back of the truck with two wires running back and the front with two wires running forward. The module then runs to your lights, fuel pump, etc.
