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.

I've attached a picture of the 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.

ja1724,

A quick search on the net and I found this:

Look about 3/4 down the page.
