Electric over hydraulic brakes

One more thing - I have a 2013 F350 and had disc brakes added to my fiver last spring. As was explained to me by the installer, the Ford system does not send a strong signal to actuate the trailer disc brakes very much until you are moving at a much faster rate then walking or idle speed. So make sure your truck is set to the electric over hydraulic setting and then hook up and try it at about 25-30 mph, then at highway speeds. I have my gain set to 6 and that works well for me, but thinking of going to 5 to see if it's easer to modulate braking. Mine stops quickly enough if I stab the pedal that I am a little worried that the car behind me could run into me.

My truck did not need the module discussed above.
