Aftermarket fog light install

2020 Rubicon, where do I find low beam wire to connect a relay for aftermarket
fog lights? I do not have any auxiliary switches inside.

Are you keeping your factory fog lights? Tap into that line.

Yeah, I agree with this post - and some questions come to mind -

Why not wire them in place of the factory fog lights?
You certainly don't want the factory AND another set of fog lights. (or why would you??)
You are going to need a switch to turn them on when needed and off when not needed anyway - you don't want them on at all times with the low beams.
Are you replacing the fog lights that come with these in the bumper? If so, use those wires to power and control the replacements.
Which fog lights did you get with your Gladiator? The LED or halogens?
I also very strongly advise against "tapping into factory light wires" - it's something you need to do with great care. These aren't your father's lighting systems and controls.

Typically that will only work for "Plug & Play" aftermarket lights. If the fog's he bought aren't in the small window the CAN-BUS system is looking for, there will be problems.

The talk of relays and such reminds me of the chain store fog light packages of years ago...... today, I'd never install anything not made for a modern vehicle's electrical system.

He's going to need to run a switch to turn them off and on anyway.
Fog lights are intended for fog, not as a look at my pretty lights thing.

I wired my Rigid fog lights into the factory harness. No problems at all all far as codes or warnings. When I replaced my bumper, they didn't have factory fog light holes so I simply cut the ends of far enough back so I could reinstall them if I wanted to and wired the Rigid lights into. Easy quick and not one problem so far. Had then in for 6 months and use them every time 8 drive at night.

I’m keeping the factory halogen bumper fogs. I have a set of new in box Hella fogs laying around. If I didn’t already have them I would not be doing this. The low beam wire will be used for the relay which will be switched from inside. I can’t id a fuse in the panel for this, so I’m assuming it’s computer regulated. I was trying not to have tie in at the headlight itself.

There are two fuses - external lighting 1 and external lighting 2.
However, there will be nothing for headlights because headlights are not to be fused. Headlights have always been on breakers, even since the 1950s, so don't bother looking for headlight fuses - you won't find any. They may exist somewhere, but of all the automotive wiring I've done, I've never seen headlight fuses. Imagine being out somewhere and you pop a headlight fuse at 1am. I guess you sit.

And depending on WHAT FACTORY LIGHTS you have, they are voltage regulated.

You are keeping the stock fog lights - but adding more? Why? Frankly, I'd sell them and upgrade the factory fogs to DiodeDynamics SS3 lights. They are fantastic, LEGAL, meet all specs and actually do work in fog and nasty snow storms where you can't use high beams.
(this adding extra lights may end up being a pain as tapping into the factory stuff can lead to issues since these are made to sense bulbs out, and more)

Here's from a MOPAR lighting expert and consultant - talking about a study done by experts, measuring differences, whether or not fog lights made a difference WITH NO FOG - basically, no, it' in your head......

As you can see, neither type of fog lamps by themselves provided adequate light, and the ratings for low beams with fog lamps are only very slightly elevated from the ratings for low beams without fog lamps. The new ("J2510") fog lamp specification in this comparison is a very up-to-date, state-of-the-art technical standard requiring substantially better performance than the old ("J583") specification. The important thing to understand here is that even fog lamps conforming to the newest, most stringent performance requirements give only very minimal improvement in actual seeing ability—and the rating differences, if subjected to rigorous analysis, would likely not be statistically significant.

Sorry, but I am a bit perplexed by how many times people toss on more fog lights and use them in any weather.
When aimed legally and properly, they don't really help.
Most after-market stuff is crap like some factory fog lights - but marketing tells us they are cool and we need them, so we do it LOL

I switched to DiodeDynamics selective yellow fog lights in my bumper - never looking back.
