Just about finished with the stand alone harness. You can see that I’m bolting the fuse/relay panel to the inside of the access panel. Still trying to figure out which wire I need to hook up to the ignition switch. All the diagrams show the switch going to the BCM (body control module) then just a dashed communications signal (no wire identification) to the ECM (engine control module). If anybody knows what wire I am looking for I’d appreciate some advice
