No marker lights

Help!
Traveling back from WI to IN I had the famous China bomb blowout on my 2014 Keystone Bullet Premier (yes my fault for not changing the tires earlier, which I just did today. Goodyear Endurance) It was the rear passenger side tire. One of the issue's I have (there are several) is the wiring to the side marker light by the wheel was completely ripped apart. I reconnected the green/white wires and the white wires together (less side marker) and the only lights that work are the brake lights and turn signals. I have lost all other marker lights and my back up camera (self installed connected to back top marker lights). I assume the wires pulled apart somewhere above the underbelly and I will have to take that down and following the wiring to see if it pulled away from anything else. Is this a correct assumption?
Thanks in advanced.

Yup you are most likely correct and the Keystone color code chart "should" be accurate for the wires running to the marker lights should be easy to repair once you've located the damaged wires or broken ground for that circuit

Have you checked for power from the truck? If you had the lights on during the blowout it may have blown out the fuse or relay in the truck. I'd check the simple stuff before tearing into the Coroplast.

Great point

Never thought of that, Thanks!

Wait.....would I still have brake lights and flashers if the fuse was out?

Yes, running lights (or parking lights, or clearence lights, all the same thing) is z different circuit than the brake and turn signals? Look in the owner's manual for your truck for what fuse controls that circuit.

Flybouy, Thanks again! I will check tonight. Sure will save me a lot of headache if it is only a fuse.

What makes me think you've lost power at the truck is the statement "lost all other marker lights". The wireing harness runs front to back so with the wires damaged at the wheels the front 3 and 2 forward side lights should still work. I imagine when the wires were damaged that the positive and negatives wires were shorted and blew the fuse. It's an easy check. You could also jumper the trailer umbilical and confirm the remaining trailer clearence lights work.

Checked the furs tonight. You were absolutely correct, it was a fuse.
Thanks for your help. Saved me a lot of headach.
