I redesigned the part so it fits the curve of a LEER truck cap. I'm using the 2022 camera. Also, I opted to use 3x M3x25mm 316SS fasteners to attach the camera to the fairing, and went lower profile (cleaner aerodynamically) on the fairing. I'm printing mine in white ASA (UV resistant) and will prime/paint to match the truck. I will be happy to print more if people are looking for a LEER-specific camera mount/fairing.
Prototype without the curve for the topper:
At least in my case, I am more than likely going to drill a hole in the topper, under the fairing, and snake the wire in that way. The LEER topper has a larger radius at the top rear corner, and the existing light is further from the top, so more wire would be exposed if I did this using kpecks method. Still, I added the wire guide just in case.
For me, during the installation:
1) I ran a long RG58 cable (30', but 25' would have worked nicely) from the back of the cab (behind the rear seats) to the back of the truck, snaked the wire up to where the light connection for the topper is.
2) I removed the factory light bar/camera from the rear of the truck. Then I ran an extension cable (10', but if I were to do it again I would use a 7' cable) from the mirror side and the camera side down the side panel on the right of my truck, terminating behind this panel. In hindsight I would just run the cables to under the rear seat for easier access. I did this while soundproofing the rear cab of my truck, so the rear seats were out, as was the side panel in question.
3) By doing this, if I ever decide to remove the topper, I can simply plug the factory camera back in.
