Where does the Power Steering Wire plug into the unit?!?

Ok doing a Gen4 swap and put a reman Alltrac PS pump on the Gen4 motor. I wasn't the one who pulled the original pump off. My wiring guy tells me the green wire/black plug in the pic below is for PS. However my pump doesn't have any sensors on it - just the 2 port vacuum switch. Can anybody help? This is holding me up from installing the motor!

Its a mechanical pump it has no connecor.

I figured it out. When using a gen 4 ecu you must add the sensor from the Caldina pump. Luckily it swaps over easily - it is sandwiched by an adaptor at the banjo. I'll snap a picture in case others run into this.
