I am swapping out my rear hatch with a non rusty one. While getting to the harness I noticed a extra 2 pin plug coiled up and factory secured. It looks like it goes to possibly a 3rd rear dome light. I checked for power with my test light and it does have power. Im guessing my 92 3fe powered 80 didn't get some sort of accessory back their since its not a VX diesel. Anyone know for sure what it is for? Im thinking of using that for powering some aftermarket dome lights, and USB plugs or something back their for charging phones and such.
