2023 GMC 3500HD PRO 84488395 Trailer Brake Control Switch Assembly

[richard.m.true]

My '23 3500HD Peo (VIN: 1GT49SE77PF125402) does not have a factory (84488395 Trailer Brake Control Switch Assembly) however it does have an aftermarket CURT trailer brake controller.

My question is, If I were to install a factory 84488395 Trailer Brake Control Switch Assembly, would it conflict with the existing CURT controller?

 

ALAO, MY truck did not come with Fog Lights, What is the exact GM part number for the Fog Light Kit?  Also, IF I were to install this Fog Light kit, would I need to FLASH the BCM?

The factory TBC setup is integrated w the other computers on your truck.  It is not able to be installed after the truck has been built, as GM won't upgrade the software the truck uses to allow it to work.  You can buy the parts and install them, but they won't work.

 

And the switch is only part of the tbc system.
