Help with GM induction coil please.
Ok, to allow my Holley Avenger MPFI ECU to control my timing I had to change out my D.U.I large cap distributor to a GM HEI small cap. I bought an external coil (for a 1995 Chevy C1500 Silverado 5.7L) but it came with no wiring diagrams and I have no idea what goes to what.
Here's a picture of this little sucker:
Anybody know how this thing is supposed to be wired? What terminals get what? I think one of the connectors gets ignition power & ground and the other goes to the distributor. But they both look the same so I don't know what is what. Any help would be appreciated. Thanks.

The left and right sides of that coil are the same. Pick one side and it goes to the two pin connector on the Small cap HEI. The other side gets switched 12V on one terminal and is tach out on the other. <bR>
