HEI in Mopar ECU casing

Wow guys! Great job!! Very interested on how these work out for you!

Also if I read this correctly, you can just hook it up to the factory harness. But you should remove the ballast resistor, (then what do you do with the wires that connect to that), just connect them together? And then switch to a different coil?

That's about it.
When I put my HEI on I cut all the wires for the ballast, module and coil off right at the harness.
Then I connected the start and run wires together and used that for ignition power to the ecoil, right at the spot where the ballast wires exited the harness.
Sure did clean up a lot of wires off the engine and firewall.

I have also built two like in this thread and sold them both to owners who wanted HEI with a stock look.
