I need a little help from the experts. I just bought a 2009 F150 and there is no trailer charge relay or fuse in spots 9 and 21 under the hood. I've search around and have not found anything that specifically says what the part number is for the relay on the 2009. Does any one know for sure what it is? I found part number AL3T-15A416-AA for the relay on newer models but I'm unsure what years it works for. Thanks in advance for the help!

 

why not just call the dealer parts dept? Give them your VIN and they should give you the correct PNs. Then you can order from anywhere...

 

Sorry, I should have included in my original post that I did call my local dealer and they were of no help. However, I didn't give them the VIN (they didn't ask for it) so maybe that will make a difference. Thanks for the suggestion.

 

Here's what you need:

Ford part number: AL3T-15A416-AA

 

Thanks! I'll check it out.

 

Just in case anyone else needs this info in the future...
I was in a different part of town today and saw a Ford dealer so I stopped in to see if they could help with my relay issue. After several minutes of searching online, the parts guy said I needed Ford part number 8T2Z-14N089-A for the relay. It cost about $28.

Thanks for the help everyone!

 

Does anyone on this thread that have found the baggie with the Relay & Fuse in the glove compartment/door compartment, and not properly installed in the fuse box, know if their manual is actually calling for the Relay & Fuse under slots 9 & 21? Or, does your manual states "Not Used" as my 2015 F150 manual says?

The reason for this question is because my model year is a 2015, and I'm trying to make sure that the same applies to me since I didn't see the baggie, and since my manual doesn't state anything regarding a Tow fuse & relay, but I'm going to install an aftermarket 7-way adapter, and will be pulling a camper with this truck. Right now, I have only a 4-way, but will convert to 7-way, and although I can go directly to the battery in order to power the 7-way to keep camper charged while traveling, I want to avoid that altogether if I can by-pass it by splicing directly into the existing wiring harness. But, I still have my doubts that it will NOT work because of all the threads that I've been reading about the missing Relay & Fuse, although all of them are for F150's earlier than the year 2015.

Thank you.

 

This has been a factory problem for at least 12 years. My 2005 and 2013 150 both had empty slots for the trailer power fuse and relay. How can Ford have ignored this for so long? Otherwise I am a very happy owner.
