Hey everyone,
I bought a 2014 Sierra 1500 back in September that was perfect EXCEPT it didn’t come with the oem brake controller. So I contacted my local GM dealer and gave them my vin. They looked up my truck and verified that it was built including the trailering package. This is important because I’ve seen that your trucks computer has to be programmed to accept the oem trailer brake controller, the piece isn’t just plug and play. So I verified this with the dealership.
*I’m really thrown off that my truck has everything in the trailer package for that year except for the brake controller*
I purchased an OEM piece from another GM dealer on eBay, ACDelco and everything. Plugged it in and haven’t received an alert but I also can’t tell if it’s working. I’m going to try plugging a trailer with brakes in and see if anything changes or if the controller does anything. But from what I’ve seen I should already see a new info page for the brake controller.
I’ll update the thread later whether or not it worked, regardless I’ll leave the thread up in case anyone else is in the same boat. If anyone has suggestions or advice it would be much obliged.
