Im wiring up my wolf3d v4 and I dont think the BAC is worthy of running 2 wires all the way to the other side of the engine bay. All the injectors and BAC need 12V power when ignition on, so I dont see why not just continue the wire chain over to the BAC. Will 14 gauge wire and a 30 amp relay handle the 5 things sucking power from it?

 

Just reminding you that the injectors switch on the ground side, not the positive side. While the BAC (I believe) switches on the positive side.

 

Thank you for the info, but im not wiring up a stock ECU. Like I said in the 1st sentence, im wiring up a wolf3d. On the wolf3d the BAC is controlled by the ground, it is supposed to get 12V with ignition on. Same with the injectors. My only concern here is if 1 relay can handle all the juice these 5 things require to work properly.
