Trailer running lights question

[bassarama]

Thanks y’all, I think I just solved the problem, my wife just dropped the owner manual.

Tsubaki give me a excelent lead...

On page 136 of my owner’s manual:

“To handle the additional electric load of the trailer lights and assure their proper functionality, a heavier duty flasher is furnished with vehicle equipped with a trailer tow package. The flasher is in a loose package in the glove box”.

D’OH, no wonder why I could find a blown fuse, it ain't a frigging fuse its a flasher whatever that is a relay? ???… I”ll look in the glove compartment tomorrow night.
