Question:

My running lights on my trailer do not work. The blinkers and brake light do work. I need to know which relay works with the running lights, the blue one or the brown one. Its on a 2011 Nissan Frontier.

You can check the blue relays on your 2011 Nissan Frontier for troubleshooting your running lights.
The replacement blue relay is included in the Curt Relay Kit # C57000. Since it is hard to actually test a relay, you can use a new one to determine if that was the problem with your running lights.

Circuits that are tied to relays usually also have a fuse. There are 2 fuse panels in the Nissan Frontier. One is under the hood and the other is in the cab of the truck. You can also check both for any blown fuses.
