Brake Controller Installed in 2021 Chevy Silverado Z71 Trail Boss Not Powering Up
Question:
Thanks Mike, checked the diagram on fuse panel cover. Position 84 is for the trailer brakes. I will get a circuit tester and try that. I hope its the brake controller thats bad. Thanks again for your assistance. Youve been a great help.

Assuming that you've found the correct connector for the # 3064-P brake control harness which is located under the dash to the left of the steering column, I'd wager than you have a fuse missing in the power distribution box in the engine compartment on the passenger side. Check fuse location # 84, and make sure that there's a fuse installed there. If the fuse is missing or blown, you can obtain a replacement from your local auto parts store.
