i just found a bad fuse for tthe trailer parking lamp lights. i replaced the fuse and the lights turned on. i then found no brake lights or blinkers. their is no fuse for the trailer tow on the 06 f350 diesel. i checked with a test light on both 7wire/5wire plug and i dont have turn or brake. what fuse could it be please help i am at a uhaul rtight now trying to pack my house and i need the trailer asap.

 

Check fuse F1.9 20 amp out in the battery junction box.. It feeds load voltage to the L/R trailer turn relays..

 

There are 2 fuse boxes one under the dash and one under the hood
check the one under the hood
the one under the hood handles the tow lights

 

Easy check is to go to uhaul and get the magnetic tow lights 32 bucks
and hook them up to see if the problem is in the truck or the trailer lights
