I just bought a trailer and 7 into 4 adapter for the tow harness. I'm not getting juice to the running light connector. Turn signals, hazard and break lights work fine. I've checked the owners manual for a fuse but can't find one labeled "running lights" Found left stop/turn fuse, right stop/turn fuse, trailer brakes, and one just called trailer, but nothing called running lights. Is it grouped in with something else or am I looking in the wrong direction for a fix to my problem?

Thanks,
John
