[QUOTE="MedCityRaptor, post: 1877040, member: 32669"] After receiving my GJ Motorsports 3rd brake light and noticing the instructions are terrible. I decided to do some good research and figure it out on my own and hopefully, this makes it easier for the next person. First off, I received mine without the connector to plug directly into the stock harness so I had the vampire connectors which made it a little more difficult. Below is a basic wiring diagram (if you have the connector) that I made. Please note all the wires that you are connecting to the truck harness have no ends on them if you received it without the connector like mine. If you have just the vampire connectors just take the connector for the truck harness out of the equation and you still connect the wires to the same spot. On my 2021, the blue marked wire was to the purple wire on the truck harness. The wire from the "in" on the reverse harness went to the white wire on the truck harness. The red marked wire went to the red on the truck harness. The black wire went to the black wire on the truck harness. [ATTACH type="full"]393154[/ATTACH] [ATTACH type="full"]393156[/ATTACH] I had the NMO mount and the cable wasn't attached as well. This was pretty straightforward since the screws are different sizes and the cable ends are to accommodate the proper size screw. Just make sure you also use the plastic washer on the antenna cable between the connector and the antenna to prevent it from grounding out. Running the cables was fairly easy. You just need to pop off both the front and rear door sills on the passenger side and then remove the cover for the fuses on your kick panel. I was able to pull my headliner down just a little bit to grab the cables and then routed both the nmo antenna cable and the wiring harness behind my c-pillar, then through the bottom of the b-pillar, and then just the harness to the kick panel. The nmo cable, I was able to route to my center console through a divot you can find below the passenger side seat.

Removing center console: [MEDIA=youtube]zQmVTeSFMk8[/MEDIA] [ATTACH type="full"]393164[/ATTACH] I ended up terminating both side S2 lights into a weather pack connector and then pulled the wire for the 6th upfitter switch to run both at the same time. You could also use the Y connector right off the lights and just use one of the wires to terminate into the upfitter wiring harness. Remember if you want to use the upfitter wiring in the kick panel, you have to connect the two wires by your battery in the engine bay for that same upfitter switch to work.
