I am trying to convert my '67 FORD points system to a HEI system. I went to a bone yard and grabbed the harness from a 74 Ford truck that connects the distributor, coil, and module together. I was told to connect the Red module wire to a fused 12v supply and the white wire to the "switched on" 12 volt supply comming from my ignition switch. When everything is connected, I have 1 gray square plug unused. 1 of the cables in this plug goes to the connector that snaps onto the coil. I figure that is why I have no fire while trying to start. Any suggestions out there?

The RED goes to the RUN on the ignition switch. The WHITE goes to either the START terminal in the ign. switch or the I terminal on the starter relay.



This wiring diagram is from a DURASPARK II system (1976 up). It will be wired to the ign. switch the same but a few circuits will not be the same. As long as you have the correct engine harness and module, it should just connect together one way.

It is easier to use the DURASPARK II system (blue strain relief) as it produces a hotter spark but you should get by with what you have.
