I had to remove the fan shroud in order to replace front differential. My brother helped and cut the 5 wires and I’m trying to figure out the 2 grey wires. I have had 5 people look, and they all say they are the same color. Left to right on the plug, is black,white, grey, blue and grey. I know I have a 50/50 chance, but can I check power/resistance from the engine side of the wires to see which grey wire goes to position 3 or 5? Thanks
