  • I’d definitely buy it again and will tell others about it!!!
It fit perfectly and was a lot better than splicing wires and it also makes it easy to put back to factory specs!!!!! Wish I purchased it with the lightbar!!!!! I’d definitely buy it again and will tell others about it!!!

  • Easy to hook up
I appreciate not having to do any permanent splicing on my GMC, especially for a stick-on light bar strip. I wish the harness was shorter, actually. It is curently coiled up behind the bumper. This was pretty easy to install, and I only really needed a flat-head screwdriver to separate the truck's connector, and zip ties and wire cutters to secure the harness under the vehicle. I do have a small delay between when my tail lights turn on, and when my light bar lights up. I don't know why. ... show more

  • Tailgate light bar adaptor
This connector fit my exact need to allow me to install a led tailgate light. It supported the wire to control the reverse lights on the tailgate lights. It allow me not to consume the 4 point light plug in.
