Trailer brake install

[DDDonkey]

Hello all,

I am once again looking for some help. I was looking around and found the OBDII connector and a bag full of wires. Within the bad was a pig tail for the trailer brake wiring, and it was plugged in so all I need to do is install the controller. Wiring the controller in looks easy, but is there a fuse or relay that also needs to be installed, and if so were would it be located. I did find a Ford fuse box on top of the steering column under the dash but but there are no real labels. Any help would be great.

Most brake controllers today you can get a pre wired plug in harness. Most Fords do have a charge circuit relay and fuses in the under hood fuse compartment.
