What it the function or purpose of the red/white wire coming out of the FP relay? It's labeled "fuel pump prime" and diagrams show it terminating at what I assume is supposed to be a plug connector. This wire was ran into a connector that contained the auto trans wires, and I couldn't find a diagram for that connection. Other than that, I think everything is looking good.

FP prime wire (red-white) is connected to NC contacts of FP relay (in OE configuration). This connection allows you to prime or test fuel system with ignition off by applying +12 volts to it. It is FP diagnostic terminal.
