    Truck cap wire

    This is perfect solution to easy wiring of a truck cap. My only negative is I just wish it included the extra ground and power for the internal light.

    Read and compare My fault

    Unfortunatly while reading and comparing this harness to the other models I did not notice this harness does not plug into the trailer wiring but tee's into the tail light wiring on each side of the truck therefore it does not give and extra power source for the dome light. And requires exrta wiring to power the dome light. Would be a much nicer set up with a 12v power supply like the others.

    Great adapter

    Well built and plugged right into the existing tail lights, it takes power from both sides provided the ground and power for the third brake light to my camper top. I would recommend this versus splicing in
