Use the factory wire to the coil to actuate a relay, and then use the relay to power the ignition module. Run a wire straight from the battery to the relay, with a 30a fuse as close to the battery as you can get it. You should put a ballast resistor after the relay, but I've run the DSII modules of straight 12v with an e-coil with no ill effects.
Ford never used an HEI system, that was GM. Ford called their electronic ignition Duraspark.
