Question:

I have decided that i only need an adapter to go from a 7 (trailer side) to a 4 (vehicle side). What do you have available for that?

We have exactly what you need to add fully functioning 4-Way and 7-Way connections to your 2014 Ford F-150.

Since you already have a 4-Way on your F-150 you will need to use the Universal Wiring Kit # ETBC7. This will connect to your existing 4-Way and then will have some open ended wires that you will need to connect to the battery of your F-150 and your brake controller, as well as a wire with a ring terminal for a ground.

I am attaching a video that shows this process being done as well as the Tekonsha Prodigy P3 # 90195 being installed. If you don't already have a brake controller (to activate the brakes on your trailer) then I highly recommend the P3 as it is one of our best-selling controllers due to the easy-to-read LCD screen. To install this controller you will also want to use the Plug-In Adapter # 22292.

In the installation video our team member uses heat shrink butt connectors for superior, waterproof connections for the wiring. If you would like to do the same you will also need part # DW05745-5.

I have also attached a helpful article that you can use for the installation of the ETBC7 kit.

If you are just needing to utilize the basic lighting functions on your trailer then you can just install the Adapter 4-Pole to 7-Pole and 4-Pole # 37185 that comes with the Kit # ETBC7 and tie off the Purple, Blue, and Black wires. I have attached an installation video of this same process on a 2013 F-150 for you to reference. You will just stop watching at about the 4:45 mark. Please keep in mind that if your trailer has brakes you will want to install a fully functioning 7-Way using the steps and equipment I stated above.
