to hook up the slu you need to hook up the recoil motor seprate the micro switch has 2 wires going back to the slu miro switch input and 2 wires going to the elevation motor the micro switchconrtols the recoil motor on from inside the slu

you have a recoil out on the slu for the motor

a miro swith input on the slu to control on and of barrel position

and there is no exra triger wire for the recoil as it is internal to the slu
