Adding GM factory trailer brake controller

[C. White]

Once I get home from work, I’ll get OEM part numbers for the modules. Keep in mind that this is not a simple buy a harness and plug and tow. Could you acquire a harness from a salvage yard, yes you could but then you a lot more to sort out cause as with JL1, if you have park assist sensors, the the rear camera, the magnaride suspension and so on, you’d have to get a harness from a truck that has all the same RPO’s as your truck with JL1 cause those wires would for those options would be present in the harness.

Even with adding the additional modules, the switch, the wiring additions (which will be significant and likely insurmountable for those that are thinking just add the switch and go) there is still the programming that will likely be impossible to resolve.

 

To date - this is still IMPOSSIBLE.

TLDR...GM's TSB still applies and it can't be added.  

 

$100-200 aftermarket controller beats the absolute a$$ache you've presented.
