There are a number of troubleshooting steps to take if you are having issue with the running lights on your camper. The first thing to do is take a look at your owner's manual to locate any trailer fuses or relays and ensure they are all there and in working order. If they are, in order to determine the specific problem you will need to purchase a circuit tester if you do not have one - the very handy Cordless Circuit Tester # PTW2979 - and test the connector on your vehicle after disconnecting it from your trailer. Check the wiring going into your harness from your tail lights to see if those wires are carrying the correct signals, if not then the issue is with the vehicle wiring.

If the signals going to your harness are okay, you'll need to test the signals coming out of the harness, and if they are correct then your issue is likely going to be with the camper wiring. You will also want to check both your vehicle and camper connectors for corrosion, which can be green or white in color. A build-up of corrosion can interfere with the signals getting through the connectors.

I have added links below to a pair of help articles on wiring, including a troubleshooting guide for you to take a look at. Additionally, to help prevent any type of corrosion in your connectors, and increase their durability and lifespan I highly recommend using Dielectric Grease for Electrical Connectors # 11755.
