1 14ga and 2 16ga up each side, I used 1 14ga for the light bar that pulls the most power and the other one for the negative. I wrapped then in high quality 3M electric tape.

I lost of of the rubber things at the base of the windshield in some bad crosswinds because it didn't quite fit back in with that many wires. I would use some gasket silicone to hold in them place next time.

I would also see if you could find a single wire that had 3 14ga was thinner then wrapping 3.

There was also two ways I tucked it in. On one side I took out the rubber mold off the side put the wires under it put some windshield silicone and stuck the rubber gasket on top of the wires. This left an ugly lip so I used a razor and cut the excess off to clean it up. On the other side I put the wires on top of the rubber and put the windshield silicone on top of the wires.

I have 6 wires on drivers side for my main bar (4 16g and 2 14g) and 2 on the passenger side (14g) that run to the rear for my chaser lights.
I would suggest you buy a long roll of heat shrink tubing and run all the wires for it though that first. that way you can run all the cables flat before heat shrinking it.

Run the wire on the inside of the rack to the front then tuck in the channel. its clean, no one really notices until they start really looking.

You realize that blocking that channel on the windshield also impedes water flow and could lead to a leak somewhere, right? If it’s done right, passing wires through the roof does not invite water damage. I work on fire apparatus as a career and not a single one of our rigs has water issues from running A LOT of heavy gauge wiring through the roof (emergency lighting, heavy duty scene lights and radio antennas). Neither do our patrol cars or public works units. All of these see extreme weather more than anyone’s rig on this forum, I’m willing to bet.

Can you do the windshield drain channel? Sure. Does it look bad? Subjective but I think it’s the easy way out and can look tacky on an otherwise clean rig.

At the end of the day, done right, both are probably okay. It if was my rig, I’d stare at the damn wires running down my windshield all the time. My ocd would get the best of me.

Damn near invisible in the channel and never heard of a case where it caused a leak.

If you still feel weird about it, use the lift gate grommets.
