My truck trailer connection has no power to the + pin, called the Trailer Tow Battery Charge. I traced back to the fuses and relays and discovered the relay missing. Unbelievably Ford is having a hard time with this relay. They don't seem to be sure which one it is. My owner's manual says it is a Full ISO relay. But Ford doesn't like that description.
What can I use there? Is there any after market relay available that would fit. Napa said they don't have anything listed, and O'Reilly and Autozone look at me with a stupid expression. I also need one for the starter relay. Mine was replaced with a anti theft device that has a remote control. I want that removed so I need the realy. All the relays appear to be the same. I plugged in the blower motor relay in the trailer tow charge position and got power to the + pin. But I need the blower motor. The Ford guy said that it might be the right one, but he couldn't be certain and if I plug it in and it doesn't work it's my loss. At $27 to $34 each I want to be sure.
Maybe the parts guru can tell me what's possible.
BTW - This is for the 2006 F-150, 4.6l truck.

Reason: Clarify which vehicle
First of all, this is the 1997 - 2003 F-150 forum. I would recommend that you try a RV shop or Trailer Towing shop in your area. They may be able to help you with the relay. Otherwise try sending a PM to NumberDummy. He seems to know a lot about part numbers in the trucks. Good luck!
My '08 came with a relay and brake controller pigtail in a plastic bag. The part number on the relay is F0AB-14B192-AA. The part number in the instructions is F0AB-14B192-A (Trailer Tow battery charge full ISO Relay)
The part number for the entire package seems to be 4L3T-15A416-AB
The Relay you are talking about is a MULTI RELAY... R01 Thru R06....They are all the same, and yes FORD Dealers are idiots and have no idea how to find them without the part number... Any questions just asked, went thru this for the past 2 months. looking for answers
