Actually, others have posted their best guess of the connection, and that is 
what you asked for. As you said, you could open up another drill and take a 
look, if that's all you need. Also, don't "bite the hand that feeds you", as 
you seem to be doing here. Most people first do a cursory search for the 
information they need and then come here if that doesn't provide the 
information, or if further discussion is warranted. This IS a design 
newsgroup, not basics, so you should expect people to discuss the design 
aspects, which apparently you have no interest in.

Too bad if you don't have time to do your own research, or even open another 
drill to get exactly what you need, and instead expect us to spend our time 
doing the work for you. Many of us charge customers consulting fees for what 
we do, especially if it is a commercial venture, which your application may 
be. Here is a circuit I found, but the drain is connected to the motor via a 
reversing switch, and the source goes to the battery minus terminal:
