running lights
my 05 f150 running lights work fine, but my 4 wire flat does not have any power for the running lights, both blinkers work fine. i checked my fuses on the passenger side floorboard, and every one seemed fine. any ideas? this is killing me since i pull a trailer every day for work.....

Ok so this may be stupid... but i've done it before. Are the running lights on your truck on? Because i believe they need to be on for the ones on the trailer to be on.... If you already know this i don't mean to insult your intelligence

Just info for you, my 02 shows a trailer tow relay in the battery junction box. Its called trailer tow parking lamp relay in the diagram (running lites). Check your owners manual for its location.
