HEI for your Mopar?

Look at the GM 8-pin module. It already has sealed connectors (Metripak or such) that stick out the side of their "small cap, computer distributor". You could put it in your box with cutouts for the 2 connectors. One connector goes to their coil, using their cable (isn't that easy?). The other connector is optional (computer command of spark advance). Hard-wire a distributor cable, as 67Dart273 shows, but I suggest a plastic "cord clamp" (search that and "PG7" on digikey) and smooth PVC sheath (SPC Tech on digikey). Also provide a ground terminal that must be connected. A bad ground it the reason most Mopar and GM modules are claimed "bad".
