Where is the Fuse for Trailer Power Located on a 2004 Chevy Silverado

Published 10/25/2017

Question:

I have accidently burned the fuses for the red wire gauge 12 located at the back of the vehicle and also the black 12 gauge wire that connects to the device monted on the dashboard four wire connector. Can you tell me where the 12 volt suppy comes from please fuses.., I would appreciate very much.

It looks like on pages 5-126 and 5-127 or your owner's manual there is the TBC BATT fuse in the fuse box that is under the hood. This is called the Truck Body Controller Battery Feed and looks to be the only fuse title that might affect the trailer battery. If that fuse looks good then you probably fried the wiring altogether and you need to replace it with 10 Gauge Wire # 10-1-1.

If you damaged the adapter from your Prodigy Brake Controller, like the P3 # 90195, then you will simply need to order a new Adapter # 3015-P.

If that doesn't fix your problem let me know and I can help you troubleshoot further.
