Hello all! I just went to the dealer to purchase a new fuel pump relay and pigtail. The problem is the two books I have don't show enough detail about the color of the wires and where they go. The pigtail I bought has ALL WHITE WIRES - AND, the normal double wire that comes out on the right (with two large red wires) is now shifted to the second position on the new pigtail. I don't trust this and want to make sure I reconnect the wires properly. So - do any of you have any wiring diagrams that tell where the mustard wire, the other big red wire, the green/white stripped wire and the black/ white stripped wire go? I know one goes to oil pressure switch, one to the fuel pump, one to the connector underneath the dash. But WHY would the new pigtail have the wires switched around??? HELP!
