Fuel pump wires

[jetmech]

Which wire is the "trigger" or "turn-on" wire for the fuel pump relay? I know that the fuel pump wire itself is the grey one because I already installed the STS wiring harness and had to tap into that wire. I'm looking for the wire that triggers the fuel pump relay. Advice??

Find the fuel pump relay, it's either pin 85 or 86, the pcm grounds, so it's not the one that has ignition power to it.

i know kind of vague, but hope it helps
