Pertronix 600 rev limiter

I tried one, didn't get it to work. Maybe I hadn't wired it right, but I returned it and bought a Mallory hyfire. It is such a more capable unit for only about $100 more. It is multiple spark, has 2 step rev limiter, window switch if you want to use nitrous in the future, adjustable spark retard for nitrous use and spark retard for starting. It's easily adjustable and digital. I mounted it under the dash and ran the wires through the firewall (I'm paranoid about heat since I've lost 2 MSD units in the past). The pertronix unit is a rev limiter only, seems like it's something you might outgrow in the future. Here's a link for the mallory if you want to check it out. Summit has the installation instructions on their website.
