I know 1 is the fuel pump, but what does the other 1 do? It is listed as "resistor relay" in the wiring diagram. My truck now has a V6, is this still needed? Thanks in advance.

The man to inquire with on this would be member "800xl".
He could explain this in much more proper terms than i can, hopefully he will stumble onto this thread and give ya a hand here.

The resistor relay goes to the coil. It bypasses the coil relay when the starter is cranking so the coil gets full 12 volts, meaning a nice fat spark for starting up. Once the truck is running it runs power through the resistor to the coil which keeps it from eating up points. The two relays are tied together somehow, so it kind of depends on how stuff is run with your motor. If your V6 gets coil power somewhere else than the stock coil wires/resistor, no worries about that. If you also don't run the stock electric pump or use the wiring for it, you'd be in the clear to yank them both.

I believe the pump relay powers both the pump and the coil resistor, but I can't recall exactly. The whole setup is very complicated and annoying to troubleshoot, much less rework. Hopefully you can trace what your motor needs to run into other wiring and eliminate them both. Failing that, yank both connectors to the relays and see if she still runs.

Sorry to get off topic but that custom title fits you to a tee! You ARE an encyclopedia of Luv knowledge.

Thanks for your input. It still uses the fuel pump relay but the other one does not effect it when it is unplugged. Just wanted to "clean" up the wiring a little and remove all the BS not needed.
