Service Trailer Brake System

2008 Silverado with Service Trailer Brake Indicator. Remove the spare wheel, 3.10mm screws, it is on top of the brake assembly. Unscrew the 3 torx screws and slide the assembly to access the relay screws. Two more torxes, remove the old one and connect the new one. Assemble and the light should be off. It took 20 minutes, cost $450 from dealers, and here's just the price of the part.

Pros
  • Ideal for Outdoor Activities
Cons
  • Operating Speed
