Troubleshooting Interior Trailer Lights Towed by Silverado Not Active

Question:

Good evening, I read you initial answer regarding troubleshooting interior light for an 07 Chevrolet Trail Blazer. I recently purchased an enclosed trailer and when checking all interior lights after completing the state trailer inspection. I found the interior lights not working none. In you article you mentioned a couple of vehicle fuses I have a 2004 Z71 Silverado with the factory trailering package and the 7 blade connector. The trailer has brakes and my brake system is operational. What fuses should I check on my 04 Silverado? Thank you for any additional info or troubleshooting assistance.

The interior lights of your trailer would be receiving power from the 12 volt accessory circuit of the 7-way which on Chevy trucks like your 2004 model is most likely just not active and you'd need to make a couple connections under the hood.

If you check out the attached help article you can see the connections under the hood you'll need to make.
