Nissan Frontier light problem


Apr 19, 2004
So, as the title says I'm having problems with the trailer light wiring on my 2016 Nissan Frontier. Last fall my lights stopped working. This spring I bought a new harness to replace what was already there. Got under the truck last night and plugged it in to find out that there is no power to the plug. Did some research and found out that there is possible a bad relay. Anyone have any experience with this or a similar issue? Is there a fuse that would control this? For reference my trailer is a 1996 Coleman Taos. No brakes, 4 wire flat connection.
