Yes, read the vehicle's owners manual on how to adjust the brake controller. Once it is set, you should rarely have to touch it.
You should also verify you have the appropriate relays for charging the trailer batteries and trailer brakes installed in the distribution box. I'm pretty sure my Suburban came with them in the glove box. Again, your owners manual will list where those are.
