First off, welcome to the club!
Second, do you have the Nissan OEM wiring harness or aftermarket? Is it 4-pin or 7-pin?

Thanks for the reply,

(2006 CC SB NISMO) aftermarket wiring 4 pin, its work perfect only first use. I dont have the relay wiring (kick panel front passenger).

Did you have to splice any wires for the harness, or was it the plug into the existing wire type? I've heard splicing the wires on these trucks almost always screws something up.

Disregard this if I'm dumb :p

No, you heard right. I had an aftermarket one installed by tapping into the brake lights and rear turn signals. It worked perfectly fine for about the first 5 times I used it then it started doing weird things like the turn signals not working, then no lights working and finally the only thing that worked was the brake lights. It also caused me to blow a fuse that controlled my brake lights even when a trailer wasn't connected and that almost got me rear-ended. Replaced that fuse and went out and bought the OEM one with the relays and have had ZERO issues since. Everyone on this site is just going to tell you to take out the one you have and buy the OEM setup.

the OEM wiring is the only one that wont have issues. its well documented on here that its well worth the money just because of the plug and play and no headaches.

I'll second Mylt1's and HightecRedNeck's advice - take out whatever splice job was done and use the plug-n-play harness. Courtesyparts.com or fontananissanparts.com or see your dealer all similar pricing if not identical

Lots of newer trucks these days come pre-wired for towing... no need to have a shop splice in to anything.

Welcome to Club Frontier!

Whenever someone cuts into a factory harness usually there are issues after. The factory trailer harness isn't expensive and eliminates potential trouble.

The missing link is that this genration truck is not wired and controlled as they have been from 1903. Instead of power relays and hard wiring, you have an on board computer with communication link to another controller doing the work. You can't deviate from the design without the computer fouling. Use the factory designed equipt. It will work. Shade tree mechanics and seat of the pants wiring is over.

I understand, but by wiring is plug n play (no tape or cut). And why he work good for a few weeks

there is at least one other plug in kit that i know of but the only one that works 100% out of the box is the OEM one.
