I need to know how to wire a electronic ignition on a '74 F-250. The ignition is not the original, but it is just a Durra-spark box. If any one knows how, that would be great. Thanks

 

I did it to my '73 390 a few years ago, it's easy.

You need 3 things:
dist.
module.
wiring harness from dist to module.

Then just install parts and connect harness. Then you have a 2 wire connector on the module left, red to I terminal on solinoid and white to S terminal on solinoid.
