2008 GM IBC
Bill,
The IBC is not approved for use with hydraulic disk brakes.
In addition, adding a 3rd party controller will require changes to the existing wiring if your truck came with the ICB. It essentially involves by-passing the anti-lock brake module located on the frame over the rear wheels on driver side. GM has a bulletin on it:
"Procedure for Installing an Aftermarket Trailer Brake Controller in Lieu of Factory Installed Integrated Trailer Brake Controller #07-08-45-001A (09/07/2007)"
Check with your dealer. They can get you a copy. Also, be aware the bulletin explicitly states it is not a warranty repair and is undertaken at the owner's expense.
After doing this you will be left with nuisance error messages in the DIC. They can be cleared but not eliminated.
I put the P3 in mine. Works great.
