Two things you will need to do. Run a heavy 12 volt wire (12 ga min) to the Batt terminal on the distributor that is on when the ignition is on for power. You will also need to change the cap ends on the plug wires or replace them. There are a lot of reasonably priced after market units if a good GM unit is not available. Just add the 12 volt wire, plug in the vacuum advance and change the plug wires. Good to go. Bob Link to comment Share on other sites More sharing options...

WayneC Posted January 17, 2012 Report Share Posted January 17, 2012 Get the correct locking wire connectors for the 12v lead and the tachometer lead, also. Link to comment Share on other sites More sharing options...
