Tow vehicle Running lights not working

I tow my 2008 Mercury Mariner with my Thor Palazzo.. The running lights do not work on the Mariner when towing .. Turn signals and break lights work .. i check the voltage all The way to the end plug of the tow cable.. it seems as if there is a problem somewhere from the plug on the front of the Mariner.. possible one of the pins .. could anyone tell me if there is a fuse(s) installed within the Mariner that are part of the tow harness? The mariners running light work fine when not being towed ..

Any help would be appreciated

Too many unknowns: What kind of harness was installed on the towed vehicle (the tow vehicle is the one doing the pulling, the one in the back is the towed [toad] vehicle)?

The Mariner is the towed vehicle.. itís a 6 pin plug .. Iím sorry I canít be more specific for I am not that knowledgeable about these things.. the wiring is a Pollack 6 pole harness if that helps ..
