3750FL Wiring Diagram

I'm in the planning stages of installing disc brakes on my trailer. Does anyone have a wiring diagram that shows where the umbilical comes into the trailer and where the wires go so I can connect the actuator? Thanks in advance.

Posting years of the same response ... to most all our knowledge, there are no wiring diagrams for any of our fivers to be had by the consumer. Many of us comparing each others units have found that you'll not find two RV's of the same model wired exactly alike. My blue brake wire from the JBox located behind the pin box went under the street side of the bedroom and down inside the street side of the frame to the axles. Your power wire source and breakaway switch wiring can all be found around the front compartment where most actuator units are installed as well as your backup battery. I have seen some installed inside the front pass thru storage compartment. Someone on the MOC recently did his own disc brake install ... perhaps he will chime in.

Mine is installed on the street side of the front storage compartment just above where the batteries were placed coming from the factory.

Forget trying to get any wiring diagrams from keystone.
