Hey guys, have an issue. I did the rewire as this guide for 2g AWD:
Now I eliminated stock connectors and am running a bulkhead fitting with the 5 wires connected directly. Before the rewire everything was perfect no heating of wiring or anything. After rewire, we rewired like diagram wired pin 85 ground wire to stock ground harness and the main power and ground wire were burning hot. As you can see in the attached pic is the red wire is + from pump and the red and black wire is the - of the pump. Then after, we replaced with 10gauge ground straight to ground on battery and the same wires are still burning hot after 5 minutes of running car. It heats up from before the blue connector, which is the harness side, not the pump side. A friend said it could be bad pump, but I don't see it as first of all it is a newer walbro 450 and it wasn't burning hot before the rewire. Am I missing something?
I also cut the stock harness ground as that is what I tapped into in the beginning and since I cut it to add the 10gauge to the ground of the battery, I just wired that stock ground wire to chassis, not sure if that is fine or not.
