How to replace a points distributor with an H.E.I.?

[Gregski]

apologies for asking if this has been asked before, but the search on most forums leaves something to be desired (I actually have better luck Googling something only to find it in this forum than using it's native Search)

anywho... I bought this Proformance distributor and it comes with a three wire plug, red, black, and brown, and no where in the instructions do they tell me what these wires are for, they just say plug it in into your trucks connector, well duh, I wouldn't be asking if my truck had a matching connector.

I have Googled a bit and found that second pic, so I can see what they supposedly are, but I am still too dumb to know where to wire them up

Red - Batt. (+) to module

Black - Ground to coil

Brown - Command to coil

Do I just cut the plug off and crimp on some loop connections, or do I look for a matching plug? I like to do it right/clean, please be gentle as I have never replaced a dizzy before like this.
