Where to Find Brake Output Circuit of 2006 Ford F-150 with 4-Way
Question:
I have a 2006 ford f150 and I have already put the curt triflex inside the cab along with the adapter that plugged right into the factory plug. My truck already had a 4 prong outlet by the tow hitch that I can plug my boat into. I am wanting to tow another trailer with a 7 prong outlet and I bought the 4 to 7 pin adapter but I cant find a blue wire anywhere underneath my truck to connect to the blue wire on the adapter. Is it possible that it just wasnt wired for that, and if so, what do I have to do to be able to have trailer brakes on my truck? Thanks a ton!

You have to look at the driver side frame rail for the wiring needed to connect to the blue wire of the # 30717 that you have. I attached a couple pictures that show what you are looking for.

Can I simply tap the black wire on the 7way adapter into the black wire I used to install the 4way harness since that runs directly to the car battery with an in-line fuse or do I need to run a new wire up to the car battery? What size fuse should I use?
