Need a little more info:
Which trailer lights are out - tail, brake /turn?
Do you have the factory tow package?
What year model truck do you have?
If you have an 04 or early 05 have you had the trailer wiring update done by your dealer?
1. All lights are completely out
2. No factory tow package, 10 months ago I installed the fuses, relays, hitch and tied my 4 pin conector to the 7 pin harness in the back of the truck.
3. 2006 SE
You can make a new ground wire. Find a good spot on the frame, such as one of the bolts holding the hitch to the frame. Be sure you remove any paint to make a good connection.

Have your trailer tail lights worked before this? There is another relay that must be added to the 06-08s that did not have the tow package. There is a tail light relay under the dash, on the left side of the steering column. The small relay plugs into an exsisting socket in a wiring harness.

Thanks for your help. Problem resolved this morning....
This morning scenario:
1. Checked for the relay under drivers side, it was there. Than I checked all the fuses again! I found an odd square 30A fuse that blew (second fuse box in engine compartment. Went to Nissan and they didnt have it. They called the other dealers, and nobody had it. Than I went to PEP BOYS and they had it for about $3 vs $18 from Nissan...what a rip off those dealers are.
2. Put the fuse in, still no running lights. Signal and Brake lights still work.(At this point I am wondering why I dont have the schematics in front of me.) This is bull****....troubleshooting without schematics.
3. Than I am wondering about the question I was asked here on this forum: Were the tail lights ever hooked up in the first place.....hmmmm??? I do use it in the day time only (watercraft) so I wasnt sure! Maybe he is on to something...
4.Than I decide to re-terminate the wires from 4 pin harness to 7 pin. (where it was spliced in originally), and here is where I found out that my tail lights were not hooked up correctly in the first place.
Conclusion:
Proper grounding (from harness to truck frame) fixed the signal and brake lights, and proper connection fixed the tail lights (red wire). I dont know why the 30A fuse blew, nor did I find the original ground wire problem, since I just made a new one to the frame.
Everything works, went to the local sheriff dept to have them verify, and get this.... He didnt even step outside to check if the lights really worked, just took my word for it! Wow....
I am having same problem not power to 12v connector changed relay trailer tow2 and checked 32, 36,37 fuses all good, this has happened before and replaced 32 all was good until now, I did just change trailer lights to LED would this cause the problem?
