My F150 has the 7 point plug on it. Does that mean I am ready to hook up and go or do I need the guage mounted inside the cab? I have been told both ways????

 

need a brake controller inside the cab if your truck didn't come with one...if it did your ready to go.

 

Anybody know of a good cheap one?? Are they easy to install??

 

they are pretty cheap but when you get one make sure it offers proportional braking. they are easy to hook up, the truck is pre wired for it, you will just need the pigtail that goes from the controller to the harness. also, if you intend on using the 12V to charge the batterys in your TT when its plugged into the truck you have to install the relay for that in your fuse panel.

 

I got the following from R&P Carriages off of Ebay, they were good people to work with and was recommended by someone on this site. This was the best price and one of the easiest installations I have done. My vehicle is an '05 F150 STX SCAB 4.6L 4X4. Just look up the part numbers on Ebay and it will take you to R&P's site.
