How to make a enclosed trailer light work

[dms2624]

Hi everybody, I have a 2006 f250 6.0 PS. I just bought a enclosed 7x14 trailer and when I plug the trailer to the truck everything works just fine, but the interior light in the trailer does not come on. Is there a separate fuse for it??? Any special connections I might have to do???


Thanks for the help!!!

Does your trailer have a 7 pin connector or a 4 pin?

the round 7 connector

2 things. Make sure you have power at your truck plug, and check for power at the light switch. If you have power at the plug but not at the switch there's a problem maybe in the wiring. Can't remember about the 06, but you may have to have the ignition switch in the on position to have power at the plug.

That's true, I've tried that. But here's the thing. When I bought the trailer, the guys at the trailer place checked everything hocked to their panel. Everything worked just fine. They said that most trucks require a "special fuse" or a re-wire in order for that light to work. Everything else works just fine with the keys on. I have gone through the manual and looked every single fuse, but i could not find.

Thanks for trying to help me Mike. Appreciate

If you have 12 volts at your plug, it should work. Did you see everything work. I have a 5th wheel that was "checked" and I found several things that would have been found if it had really been checked. Your truck definitely doesn't need a rewire. If it needs a fuse, it will be located in the fuse panel under the hood and marked 12v or trailer power. The same wire that feeds a battery on a camper will be the one that powers the light in your trailer.

Yes, I know how those people are, expecially after they have you signed the paper work and paid for it. I saw it working. I think I could be the fuse you are talking about it. I'll check that and see if that would do it.

Thanks for all of your help.

If you have power at your plug, take it back and tell THEM to wire the trailer right.

Check this, try it with the clearance lights on..........

I have a 7x14 trailer with interior lights also, but they only work when the truck lights are turned on. As Star stated, try them with your park lights on.
