Review on ACDelco GM Original Equipment Trailer Brake Control Switch Assembly - Black Carbon, Part Number 23476237 by Carl Lipschultz

Revainrating 3 out of 5

Exchange only on tools and equipment

It's not plug and play. Look for the code in the glove compartment. If you have a JL1 it will work, if you have a Z82 it will not. Looks good, fits good, but GM got us all wrong. I have a Z71 off-road package that has all the traction gear except for the brake. All lights work but no brakes.

Pros
  • Confident
Cons
  • Big and bulky
