ok this is what i did today to try and find that dam trailer brake controller plug , i took everthing that i could remove out of the wat on the drivers side,layed on my back with a light and still no plug, passengers side i removed the glove compartment door got on my back again and still nothing. on the drivers side way up high i seen a plug that was taped to the wiring harness so i cut it loose but thats not it these had 4 small wires and a really small plug. I'M LOST i did crawl under the rear to see if it had the big blue wire going in the plug and yes it does also i check the underhood fuse panel and the book showed which fuse it was and its there its a 30 amp fuse... i cant take it anymore i'm heading to ford to let them show me where the hell this thing is.... update to follow... paul
