I know this is an older thread, but i just spoke to a GM service tech that said there is a electric trailer brake kit for our colorado's. Still trying to find the part number, but the kit consists of the dash panel, control switch, bumper receptacle and an access code that the dealer will need to unlock this option. The access code is the key component. It will update the BCM firmware to unlock the trailer brake control feature and also give you another function on your touch screen for trailer brake control. If anyone has this part number...or access code, it'd be greatly appreciated!
