I have an '04 Titan with the Tow Package. Last week the Parking Lights on the horse trailer stopped working while the Parking Lights on the truck itself worked fine. The brake lights and turn signal lights worked fine on the trailer and truck too. Just the parking lights on the trailer stopped working.

I think that the trucks wire harness plug-in (by the hitch) seems to have a problem. There is no power going the the Parking Light wire on the plug itself (a red wire). All other wires get power: reverse lights, both turn signals, positive lead, etc. But the wire for the Parking Lights is dead.

Now, this summer, I hard-wired a Line of Fire light bar into the trucks towing wire harness. I don't think this caused any problems as all lights worked fine at the time of installation and have continued to work fine until last week.

Just to make sure, though, I removed the Line of Fire wire that attaches to the trucks Parking Light wire (that red wire). Even then the Parking Light wire was not getting power.

Any ideas on what is going on?? Again, all the lights on the truck work fine (including parking lights). Is there a separate fuse for the Parking Lights wire on the plug? I didn't see any damage to the wiring harness under the truck. I'm at a loss as to what to do next. Any help would be greatly appreciated. Thanks in advance.
