I must have the face of a complete sucker, because when I went out to local RV shop to talk to someone about putting a brake controller in my truck they quoted me a whopping $573. I gave them a blank stare, politely took one of their business cards, and then laughed all the way back home. 60 seconds of Google searching later, I crawled under the dash to check the truck’s wiring.
Once I was sure that the wiring for the brake controller was already in the truck (thank you, Universe), I went onto Amazon and dropped $125 on a Tekonsha P3 and a Ford wiring adapter.
Two days later, I wedged myself back under the dash board and… literally just plugged it in.
It seems to be working. It turned right on and immediately started complaining that it couldn’t find a trailer for it to control, so I must have done something right. So I find myself wondering… why the hell did the RV shop want $450 just to plug a damn box in?
