There’s a few posted about this if you search the forum.
In other markets rear fog lights are a requirement. As such, our bumper reflector are actually light housings without bulbs or wiring to them. It’s a rabbit hole if you want to retrofit an OME stock for the OEM switch, so I didn’t go that route. I just got a couple switchs from CH4x4, a few relays and a set of VLED V6 Triton 7443 with a hardwire pigtail. Once you remove the reflectors you can see when the bulbs mount. Grab your dermal and cut out the plug. Remove the paper seal on the breather and throw it all together. I ran power straight from the battery as I wanted and always on option so that I could use them as camp lights if I needed.
I wired the rear fog light switch as the high output of the 7443 and a side light (camp light) switch on the low output. All power is run under the truck and in through the back as I didn’t want to run anything through the firewall. Relays are behind the panel in the back when the third row belt reels once lived. Happy to share more pics if you’re interested.
