:help
I am looking for, I hope, the fuse for the constant 12 Vdc lead in the trailer 7-way connector (looking from the back of the truck connector it will be the No. 4 connector). I have reviewed the owners manual, however it is not obvious which fuse is the ONE. I have to assume that this fuse is under the hood.

Can someone smarter than me point out where this fuse is located? I appreciate you all being patient with me.

Thanks, again

If it's a NBS (07.5 LMM) you have to hook up the wire to the stud on the front (towards the headlight) of the underhood fuse panel. If it hasn't been done before the wire is tapped up to the loom down underneath the master cylinder. If it has been done the fuse is next to the stud that the wire hooks to.

Some power fuses had a dummy fuse, that looked like a real fuse. Turn the fuse cover over and the diagram will show the location of all the fuses.

yes I found the location of the dummy fuse for stud 1, however in the owners manual says do not use if use at this location. if I were to put a fuse in this location should I use a 40 amp fuse?
