I assume yours is a Ford F53 chassis like mine. In my owners manuals there was a plastic bag that had the adaptor for the brake wiring under the dash. I ended up not using it and bought a direct plug and play adaptor for my Prodigy brake controller. It's just an older ford style plug. Ford only has two types of I remember correctly and it's the one for the older models.
Then under the back end all the wires you will need are located there you just need to tie into them. The only one I added that isn't a must is a constant 12v from the batterie to power the lights inside my cargo trailer.
