Chase Light Wiring Options

I recently picked up a set of S2's to run as chase lights on my 2020 ORP, and would like to avoid running the wires along the roof rack and down the gutter between the a-pillar and windshield.

Anyone here successfully able to find a good path down between the rear hatch and either wire 1.) through the cabin along the side trim or 2.) underneath the truck?

Pictures or additional insight would be greatly appreciated!

Thanks.

You can go all the way back and down the hatch, hoping that the wiring never interferes with the hatch closing/opening, since you'll have to run larger gauge wire due to the distance

You can run down the windshield like you said

You can get a marine hull passthrough and run specific wire that's designed to fit it and is waterproof. This would require drilling into the roof and then you'd run the wire down the a-pillars on the inside and through the firewall

Thanks. I was planning on splicing 14awg wire with wires provided by Baja Designs.

I got curious and looked up the S2 power limits for the Sport and Pro... they are a lot more efficient that I thought.

S2 Sport = 12 watts (~1 amp @ 12v) each
S2 Pro = 24 watts (~2 amps @ 12v) each

You can most certainly run smaller wires, or even tap into an existing circuit provided you have the headroom in the circuit.

I could see myself using 18-20awg for this depending on the length of run. Even 22awg would be acceptable for the Sport.

ETFE aka TEFZEL is what is generally used in professional race cars and F1 racing harnesses. Insulation is thin but if high quality, ideal for making harnesses to managing the loom size.

That said, I usually see TXL wire used for most standard automotive applications, especially for most hobby level installs.

I am planning to run a pair of S2s as chase lights on my truck too. However, I got several premade wiring harnesses from BD because I didn't feel like trying to find the part number for the connectors they use. I'm planning to connect to my SwitchPro using an S2 upfitter harness, two 10' S2 extensions, and an S2 splitter. What kind of rack do you have and how are you attaching your lights? I am waiting until at least February for my Gobi to come in before I can install the lights. I'm planning to grab a couple of universal mounting brackets from Axia Alloys Axia Alloys – Axia Alloys.

I have a Prinsu roof rack Ė thankfully the rear crossbar offers slots to mount stuff like lights.

But Iím sure you can do something similar with any popular rack brands.
