I've just installed my new fuel pump but I can't find anything coming out of the harness than runs to the rear lights... Is that the harness that usually carries the fuel pump wiring back? It's a '94 YJ pretty well stripped by the PO so a lot of stuff is missing but I don't want to buy if the wires are hiding somewhere in the harness.

IIRC there's a small harness running from the fuel pump to the main harness on the driver side frame has nothing to do with taillights

Okay, I managed to figure out the fuel pump wiring from the pump to the front. Now I’m trying to figure out the back-up lamp sensor now. That harness is missing too - and I can’t decipher the diagram. It’s two wires - just need to figure out where they go to. Any idea?

You can find some alternate diagrams in my signature, I think they are laid out a bit better than the ones in the FSM.
Best I can tell on mine is they come off the backup lamp switch on the passenger side of the transmission into a small harness plug into a larger plug then into a small wire loom that runs up past the starter...I lost them in a clump of loom right next to the main ground stud on the block. I would assume from there runs along the firewall to the bulkhead connector and through the fuse block then out to the backup lamps in the loom that runs along the driver's side inside the tub. Check the wiring diagrams to confirm that.
