I assume you have a NAV 500 antenna , on the deutsch connector of that antenna pin 9 is external engage. There should be a momentary switch between
pin 10 and pin 9. Be careful because pin 10 is + 12Volt, don't make shortcuts with other wires.
If you follow the cables to harness 75742 you will find that same wires on the spare deutsch connector, but check that cable with a ohm meter if it are the same pin numbers.
From the foot switch you use only the 2 wires of the momentary switch, check with ohm meter. The third wire is ground.
If you are not sure about this or the wiring ask a Trimble technician.
I made my own wiring from a NAV 900, it has the same pin layout as a NAV 500 and connected it to a EZ pilot harness and that worked OK.
There is also a footswitch with a connector to the EZ steer controller, look on the AgToGo webside.
