No.......It's just inside the rear apron, on the left side, near the LH frame rail.
That connector has 4 wires to it
18 BR = RH stop/turn
18 GY/BK = LH stop/turn
18 BR/WT = Backup
18 DB = Parking lamps
There is also a connector above the parking brake, on the LH kick panel, but if that was a problem, the fuel pump would not be working.
You could have a problem with the wire where it runs behind the fuel tank, it could be pinched or corroded in that area. Check off the connector first, and back trace.
oh opps . on my jeep its by the rear end of my gas tank. but i may have moved it at some point
