Wiring diagram?

Does anyone have a wiring diagram for the tail and brake light circuits for an 04? I recently went to install Recon LED tails in my truck and ran into an odd problem. The right side works fine, but when I plug the left side in correctly, it blows the tail light fuse. When I plug it in backwards, the tail light works but no brake or tail. The taillight tests fine on a bench. I'm stumped, and since it's not in the tail light, it's gotta be in the truck. However, the truck works fine with the factory tail lights. I also have a recon tailgate bar that works fine as well.

An update. After messing with it, now I have no running lights. The trailer running lights work fine, but nothing on the vehicle.

Don't know if this might help:

Check the connection where your trailer lights tie into the main harness. If it gets corroded or wet it can cause a problem.

The trailer side of the truck works perfect. Its the truck side that has issues. Headlight switch tests good

Spindrift. Do you have and diagrams of the VSM?

Yes, but I'm away for the next week and won't have access to my manual until then...probably Tuesday at the earliest.

wonder if you have a short in the tail light harness then. The tail light harness plug into the main harness on the frame and the trailer harness also plugs into the main harness. I had no brake lights on my truck a while back and ended up being the multi function(turn signal) switch.
