Switch help

i tried posting this in the second gen forum and didnt get much feedback so i figured i would try here. So i just got my in cab winch switches from OTRATTW today and the IN/OUT switch is a little more complex than i thought. I'm pretty confident that i can wire the on/off switch but im not sure about this other one. looking at the remote from the winch i only see three wires and im assuming that there is power and 2 grounds and which ever way i ground the circuit controls whether the winch goes in or out. So, when i see the OTRATTW switch that has 6 connections (excluding the LEDs pos/neg) im confused as to where all these wires are going to be coming from. any help would be much appreciated.

here are some pictures that might help











can i just use pins 1,2,3 and ignore 4,5,6?



Thanks,
Connor
