All,

When I first did my HEI Mod, I made a few mistakes and fryed a HEI Module. I am redoing it this weekend and wanted to make sure I got it right this time. I did a schematic diagram with the wiring blocks that I plan to use.

Please look this diagram over and make sure I got it all right.

Thanks, Craig

Looks good. Remember the switched power input could be had from the ballast resistor. Tap splice it. You could probably add this as well? Like done on this one...here. I have a few problems with this one. The 87 power from the relay is going into the ground on the coil. Both the - and + from ECU are going into the + on the coil. This is from thread 15779. Scraigallen, I like your diagram. It's easy and clean.
