i have an 05 f150 i cant seem to get the running lights to work everything else works fine (on the truck) on the trailer plug is there a seperate fuse for that?

 

See your owner's manual.

 

did that on line no maual its #10 hole they call it evrything but running lights!

 

running lights on the trailer are tied to tail lights, right? yes, there is a fuse under the hood on the drivers fender well. i have had it blow a couple times. on my trailer, you need to have the truck not running when you plug in the trailer. if it is running, it normally blows the fuse.. i dont remember the exact one, but its probably yellow (20 amp), and the small C shape.

 

check #20 fuse for tail lights. i also lost #19 once. it is one brake lite.

 

They call them "park lights". Same thing as running lights.

Owner's manual gives both the fuse and the relay information.


Guys, you MUST use the correct model year. There are variations every couple of years and, if yours is different, it doesn't apply.
