I have turn signals and brake lights on the trailer but I have no running lights. The lights on the trailer work on another vehicle. I checked the socket on the frame rail under the truck and I am not getting any running light power there. Is there a fuse, relay or seperate relay for running lights? Ive looked at the fuse panel under the hood I am not aware of any others and found nothing labeled for trailer lights. I found relays for the signals but no others. Is there a seperate fuse for running lights? What would it be labeled? Please help me correct this problem...I need the trailer soon.

If the harness you installed is aftermarket and not from the factory, then the taillights will not work unless you have a factory tow package. If you do not have a factory tow package, you can use a different harness, # 119176KIT. I have included installation details and an installation video below.
I checked a colleagues truck, he has a 2004 model, so there may be some differences. But, there are some fuses under your hood, passenger side, that may say something like HD tail light. One is a 20 amp fuse and one is a 40 amp fuse. It could be that you need fuses in these spots for the lights to work.
