190E Removing rear door window regulator question?

[slk230red]

I have my right rear door window regulator ready to pull out on my '93 190E, but I don't see any way to disconnect the 2 wires going to the motor. Do you cut the wires or what. In a picture of the new part I see online, it shows the green and black wires coming off of the motor but no connector.

The grey plastic guide on the vertical channel broke on one side....so I suppose I'll have to replace the whole unit. Everything lately has been plastic or rubber related failures.

Any tips/recommendations?

Thanks
