On a 2015 GMC Sierra 3500HD with trailer towing package, I am assuming that I can install an aftermarket trailer brake controller, plug the harness directly into the brake controller receptacle under left side of instrument panel, and all is good to go. I have not found , or seen, any information that says any other connections, or fuses, are necessary. Curt Manufacturing says it is plugin and go with their controller. eTrailer says it is plugin and go with their controller. This is the information I am finding.
If you are worried about wiring, you can always go with the prodigy wireless brake
controller. I have had mine for 2 years and it has worked flawlessly.

This truck DOES have the factory intergrated brake controller. But, I want to use a Prodigy 2, as that is what I have on hand already.
Is it just plug in and use without any other considerations ?????
OK, I'll ask the obvious question, if it's got the integrated control, why add one? Mine worked flawlessly pulling our 15K 5th wheel with hydraulic disk brakes.
I bite....
With the integrated controller, you have full proportional control based on the pressure of the brake fluid in the lines. Better than any electronic controller. The harder you step on the brake pedal, the harder the trailer brakes will come on, or release the brakes a bit and the trailer brakes will release in proportion. There is also a gain control so you can add or decrease the trailer braking to stay in balance with the truck brakes. All this is handed to you with a JL1 optioned truck.
I have only used a few integrated controls, and I have found that they are better than any electronic unit. They work like my "BrakeSmart" unit which also reads brake line fluid pressure.
It doesn't get any better.
So, why bother adding anything?
