Ok so the above link is to run just the ecu harness. That diagram is basically showing how to power the ecu and the rest of the needed things with out having to run the body harness that is ridiculously large and heavy. I want to simplify the wiring in the car so there isn't much that can go wrong in a event of a mishaps. Two relays and a few fuses all located in a central location next to the ecu in the car.
