03 f250 trailer wiring issue found
FYI... My 2003 f250 does not have a fuse block under hood it has 2 relays for the trailer directionals/brake lights. I lost these lasy year pulling my trailer. I found the issue.... I had no power going to relay block,so i ran a 20amp inline fuse line to relays since wire is suppose to be hot all the time.
