What’s up guys! Gonna start a build thread here as I wish I had done with my 3GT. It was insane but I’m excited to start this next project. I picked up my 4GT Pro on 10/8/25 and the first thing I did was the OTT tune at the dealership after signing the papers. Next in the works will be a Goose gear rear seat delete, tint, wheels & tires. Stay tuned & follow us on IG! pic of our 4R just for shits & giggles (Twin TRD, duh)

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.
