New sr5 owner. I need to get a brake controller installed, haven’t found any walkthroughs of how to do it on the 6gen yet though and I’m a paint by numbers kind of person.

Sounds like the concensus is adding a redarc would be better than going oem? As long as you don’t mind drilling or whatever? Or should I consider a wireless model that hooks up to your phone/infotainment system?

There are discussions on this forum about brake controllers. I wanted it, but the one that was available that I purchased did not have it. I do not need it right now though, perhaps never. I would prefer to go with the OEM built-in one, but my understanding here is that this cannot be added later, which seems a bit odd.

I was waiting for somebody to attempt to install the OEM trailer brake controller. But i just eneded up buying the redarc brake controller.

I'm pretty sure it's possible to install the OEM brake controller; it probably won't be plug-and-play.

Did you buy the 4Runner trail kit with it or just the brake controller? How did the install go?

If you have a trailer kit, you dont need to install anything for brake controller. I havent installed my redarc, but is plug and play

Any thoughts on if the OEM one would be "better" than a 3rd-party (assuming it can be obtained and installed, and ignoring any complexity in that)?
