    Since I got my truck back from Ford my plow lights haven't worked. While checking connections today all four headlights and turn signals blink when left signal is on but not right. Ford had motor out so I assumed a bad connection but can't find anything. Also, the two headlamp relays in front of the battery of drivers side "click" with left signal on but not right. Any help would be appreciated. Let me know if more info is needed. Truck is a 2003 F-350 7.3

    unplug your iso module and start from scratch. if everything works with the iso module unplugged, dealer effed your main harness up somewhere

    you have a relay system not iso. sounds like somebody unplugged some wires and hooked them back up wrong.
