My electric window repair

I finally repaired my rear window on my car, I bought a replacement regulator on ebay but i wasnt sure how to wire it so i wanted return it, The company has refunded me but not taken it back !!

So i cut the control box off my old motor my thinking is that there would be 2 connections off that i could connect to motor on the replacement regulator, I have done that and it works, but i have to keep pressing the switch not sure why but it will do for now !
