Whether you have a factory 4-Way flat or 7-Way then you just need the Tekonsha Plug-In Wiring Adapter # 22292 to install the Tekonsha Primus IQ # TK90160 in your 2014 Ford F-150. For a factory 4-Way flat you will also need to install the Universal Wiring Kit # ETBC7 for a fully functioning 7-Way.

I have attached an installation video that shows how to install the # ETBC7 as well as where the adapter will need to connect on the underside of your driver side dash. If you have the 7-Way and don't need to install the # ETBC7 then you need to skip to the 19:20 mark in the video.

The connector can be located directly under your dash, or in some models it is located behind one of your center panels (see attached picture).

If you are choosing to hardwire everything (which we haven't done because of the plug-in adapter) you simply need to match the functions together. Don't worry about the wire colors matching because those aren't always consistent in vehicles. Based off of that you told me you need to connect the White from the IQ to your Black/White wire, the Red from IQ to your Green wire, the Blue from the IQ to your Blue wire, and the Black from the IQ will need to connect to your battery (whichever wire that is). You can use a Circuit Tester # PTW2993 to make sure you are connecting the correct wires together. I recommend going with the adapter to make things easier.
