I decided to just wire it without an external module. I agree, I'm not sure how it would work with the internal one. The distributor came with no instructions as it came modified by the ebay seller I got it from. If money allows I want to upgrade to a msd pro billet unit. I didn't keep my original dizzy and now wish I would have.

I'd love to think I'll drive this crazy miles and on lots of trips, but we'll have to see. With my work schedule, I'm not sure I'd drive it daily. It's not like my camaro where I can buy everything new for it out of a catalog and fix it easily if or when I smack a deer, raccoon, what ever. I've had so many close calls its made me really re think the 40. LOL
