Hi. So I have a 2018 4Runner trd pro with a front runner full rack on it. I purchased 1 40” Baja Designs Onx6 and 6 S2 sports to go on the rack. There will be 2 S2’s on the left, right, and rear of the car. Everything will be getting wired to a switch pros. Now my question is, how do I get the wires to the switch pros with a pretty clean look. I don’t want to stuff them all on the side of the windshield, so I was wondering what you guys would do. I do not want to put a hole in the roof. What I’ve been seeing is people running the wires though the rear hatch and down inside the car. Would 3 14 gauge wires fit through there? I will run the Onx6 wires thought the front. The S2 lights on the sides are the issue now. Let me know what you think. Appreciate your time. Thanks

The best thing you can do is drill the roof. I ran wires through the back but I only have two light pods mounted to my rack so I used lower gauge wiring. 14 gauge is going to be too big to use my method. Drilling with a proper plug and silicon sealing is the way to go. I’ve done it before. Police, fire and ambulances use this method all the time without an issue.

drill thru the roof or run the wiring to the front and down the channel in the windshield on the driver side and drill it thru the cowling thing above the firewall to take it into the engine bay

Most people will run them through the channel in the windshield. As long as you don't have a million wires, you'll hardly notice them and it'll look pretty clean.

For what’s it’s worth S2 lights are way overkill for side lighting. Those little housings are very very bright.

There are probably a million threads on this, but don't drill your roof, you're just inviting water damage. You have a channel on either side of your windshield that you can run wires up and through as well as the grommets under the rear hatch. Way more Access ports than you will need without Drilling.

The thing is I don’t want the wire just to look so bulky on the side of the windshield. It’s going to be 6 wires.

Do 2 on each side of the windshield and two thru the grommet on the hatch. This isn't rocket science.

I have an aftermarket radio so i got rid of the factory shark fin antennae and used one of these grommets they use on yahts to run wiring thru the deck in the factory hole. Ran a multi wire cable thru it so i can hook up a bunch of lights. SO I have a couple extra wires for my baja lights later

Its entirely waterproof

That's a pretty solid idea! I dig it.

Can you send a link where this marine grommet can be purchased? Can’t find online. Thanks!!

Here's the one I bought on amazon for $48. You do have to drill the 4 small holes for the little screws at all 4 corners. But they are guaranteed water tight. used on yahts to run antenna cables and wiring thru the deck etc

Its called Scanstrut Multi Deck Seal "The Multi Deck Seal is the latest addition to Scanstrut's existing Deck Seal range, which launched earlier this year and has passed stringent IPX6 and IPX7 tests to ensure protection from water ingress, even during extreme weather conditions and heavy seas."

@GO3KIDS
what gauge wire did you run?

I’ve had two of these on the roof of my Sportsmobile for years = no leaks
