I have been SUPER nervous about cutting a hole in the roof to run electrical up for the light bar. However, after watching this, I'm convinced this is the way to go. The dude got some seal for running electrical on a boat. I just need to find one small enough to hide under the front trim for the roof rack. Then I hope to run wires back to the rails in the roof rack. I think I may expand on the electrical to have (1) USB power for say a gopro (2) wires to run power back down from a solar setup so I can have power to charge things when I'm camping.

I found out all it is called is a waterproof cable gland. That company makes really high end ones. I would buy one but sorted right now as they require drilling more than one hole.

Some of these other ones only need one hole but are plastic. hrm.... who has worked with these before?

I used "Liquidtite" conduit and fittings to pass through the roof of a past truck. The fittings have O-rings on the outside and a wide washer on the inside to seal things well. There were a total of 4 penetrations for power, control, and RF cables. I had zero leaks over about 8 years I owned the truck.

Extra steps I took:

• Chassis punches instead of drilling through the sheet metal.
• A very thin coat of something RTV-like under the washer inside. (No, I don't recall exactly what I used)
• Gland openings facing towards the rear.
• One cable per gland. Otherwise sealing is compromised.
