Trimble Remote Engage Foot Switch for EZ-Pilot Pro.  This switch will come with the proper pins crimped onto the wires.  You will need to install the wires into the green connector that is installed on your EZ-Pilot Pro wiring harness. 
 
Using the green connector supplied on the EZ-Pilot Pro harness, the black wire goes into pin 2, white into pin 7 & green into pin 11. 
 
If you would prefer us to terminate the wiring for you, we can, you just need to bring in the green connector when you pick up the switch.
 
Same as Trimble part number 78150 but for 1/2 the price.
