Electronic Ignition Help

I just switched my Valiant over to electronic ignition, with a four pin module and distributor from a Duster. There's one thing I'm not clear on though. Does the coil positive go to the Start, and the module to Run? Or vice versa? If I have the coil on Start and the module on Run it idles well but misses under throttle. If I have it with the coil on Run and module on Start it idles high with a pretty good miss but pulls through all RPMs smoothly so I'm currently running it that way. Also, when on the freeway the tach needle freaks out at 3000 as I move up towards 75 Mph. Whats that about? Any help/suggestions would be greatly appreciated. Thanks everybody.
