I have a ZZ4, and I just ordered an MSD GM External HEI coil P/N#8226.. I had to replace the supplied dist/coil with a small cap computer controlled distributor so I needed a new coil. I chose this MSD because it mentioned that it was for Small Blocks up to 1997.. It is designed to be a replacement for an existing GM coil so it has no wiring instructions. There are (2) two pin connectors on the coil. Is this the correct coil for a ZZ4? Where can I find a wiring diagram for this coil? I thought coils only had two connections (pos & neg). Where can I get the proprietary GM connectors for this coil? Any help would be appreciated.
