Troubleshooting Running Lights Not Working On 2019 Nissan Frontier With Hopkins Wiring Harness

Question:

Hello, I bought the hopkins plug and play wiring harness but I have no running lights going to trailer just brake and turn signals. I used a probe light when the lights are and I got no power from both the 4 way and 7 way. Please help.

There isn't much to the # HM43534 so I would check out the vehicle wiring. You could start by checking the Hopkins wiring right after the vehicle connector, or test the connector and wire on the vehicle side. More than likely you don't have any power coming from the factory wiring. Assuming that is the case, I would check the fuses. If a fuse isn't blown then it is likely a short in the wiring which you can attempt to find and repair or take it to a local repair shop.
