Wiring question

I have a 2013 Haulmark Motorcoach. The marker lights and tail lights are not working on the Coach but they are working on the Freightliner part.
Iíve checked all the fuse boxes that I can find. (4) Does anyone have any idea how Haulmark wired these to the Freightliner? Iím missing a fuse or fuse box somewhere.

Sorry your first post is about a problem .

There is a problem ( and recall ) involving the rear Freightliner PDC ( Power Distribution Center ) on several years of Freightliner chassis .

Call the Freightliner Free Help Line ; with your chassis serial number to see if your chassis is involved.
1-800-385-4357

If your chassis isn't involved , then ask for a wiring schematic for the chassis , that info will tell you the number of chassis fuse boxes Freightliner installed.

Are your turn signals working ?

Thank you for your help. The problem was a constant duty relay in the rear of the coach. I didnít have an idea where to start looking. You were a big help.
