Towing fuse box location

I have a 2005 Horizon Itasca, I have hooked up my tow dolly to check all lights, brakes ext, only to find the running lights aren't working. I have been told it's a blown fuse but for the life of me I can't find this fuse box! It's a Freightliner chassis if that makes a difference. Thanks for any help

And when I hook the tow dolly to my truck ALL lights are working so I know the problem is on the RV

Crawl under on the passenger side in the rear. There should be a wire harness going towards the rear end cap. There is a plug there with some fuses in it that will go towards your toad plug. Also for your tail lights, stop and signals. Mine has tags on it telling you what the wires are for.

The fuses and relay boxes are built and supplied by Freightliner but the coach manufacturer mounts them wherever they must to fit the coach's layout.

On my '04 Vectra (co-model to your Horizon) the fuses are at the very rear (driver's side) of the coach in the same bay as the side radiator. The bay door needs to be unscrewed and swung open (and propped, no struts.) The fuses were in a cutout opening on the right. There are separate fuses for the lights and left/right brake/turn. As I recall, they were 20a ATM fuses (the smaller blade type.)

I have a 2008 Winne Destination and had the same problem.

You need to find the Freightliner Aft fuse and relay box.

I found mine in the compartment with the power cord behind a panel that does not look removable. It was a real bear to get access. I made an access door in the panel before replacing the panel.

What you are looking for is a covered box with many cable plugs going to it.
It is the same as the one inside the (large) forward fuse box.

Use care removing the panel if you have 12 volt circuit breakers in the compartment. (The aft fuse box is below)

Returned after dinner>>>>>>>
I think the post below nailed it.
At least, I hope so for your sake. A lot easier than what I went through. I know people (Dealer shop) tapped into the MH lights because they could not find the fuse box.
Good luck.

Ours is in a box with a yellow 2 painted on it in the rear-most PS compartment, Tiffins may be different than yours but it is a Freightliner.

Trying to avoid taking it to a shop to replace a blown fuse but I'm stumped and I can usually repair most anything....if I can find it! lol

Diesel pusher and I don't see any type of compartment in that area. Been all through it and nothing!

In engine compartment should be a chassis fuse panel (Behind Hood Panel...cover with twist lock clips on it)

Look in chassis manual for which fuse feeds 'tow side markers/running lights'
Is it time for your medication or mine?
