Just wanted to draft this up now that I’ve got the Cali Raised 32" Dual Row 5D Optic OSRAM light bar installed in my Stealth Bumper. The fit was perfect, brackets lined up exactly where they should and it sits clean and flush behind the bumper opening. Couldn’t ask for a better match. I wired it into the factory aux switches and it works flawlessly. Everything powers up smooth and it’s nice having it tied into the truck without adding any extra switches. If you want to see how I did it, here’s my post on wiring to the factory aux setup: Factory Aux Switch Write-Up The light output is wild. It throws a ton of light down the road while still spreading wide enough to cover everything in front of the truck. This will quite literally turn night to day.

Looking at installing a trailer brake controller for my truck as it seems like I might be doing lots of towing pretty soon. Currently looking at getting an OEM one.

Wondering if anyone has added in an OEM one or gotten a wire harness that goes from an aftermarket unit to the oem switch?

My plan is to keep my dash looking pretty original and that is why I wanted to use that OEM switch if at all possible.

Only difficult part right now would be finding the wiring cause I’ve searched everywhere but couldn’t find anything and don’t think I'm about to run all new wires , If in the end i can't seem to get one, then I might just settle for a wireless one that plugs right into the seven pin and uses an app.
