Question:
Will this product fit?

I have checked with my contact at Hopkins, and it looks like both the 2009 and 2013 Ford F-150 use a 921 bulb. Hopkins does not currently have a back up alarm system that is compatible with this tail light bulb style.
If you would like you could use the Curt # C57102 or the #C57101. These are replacment trailer connectors that have also have a back up alarm included. If your trucks currently have a factory installed 7-way you will want to use the # C57101 as a direct replacement. If not then you can use the # C57102 and plug into the existing 4-way, and then splice into the other wires accordingly.
I have provided links to the parts referenced above for you.
