2006 Lariat - CaroWf150
Just as Described
This works great on my 2006 F150 Lariat! I did have to purchase a connector to fit my truck (less than $20 on amazon) but after that it plugged right in, no hard wiring required. I did have to zip tie it underneath my dash due to the steep slant, but it has been working fine.

Worked just as it should
I bought this to get rid of the adapter you need to use with the stock hook up on the truck. Hooked it up, plugged it in, and it does just what I wanted.
