Im looking into making a loom for the racecar and all I want to run is, lights, indicators, wiper (just the highest speed) fuel pumps, and ignition which will be relayed and linked to toggle switches. I also want to have the relays for mains, start, abs, igntion & fuel pumps. I will also add a few things ie, oil pressure warning light, water temp warning light. I want to remove the bcm as well so my question is if I make this loom will the car still be able to run with the factory ecu as I've pulled my old loom out and notice alot of the wires go through to the ecu connections. I will have VATS removed aswell. Hope this makes sense. Thanks
