Originally designed with NASCAR in mind, the MSD 6ALN is equipped with the mandatory 6-pin weathertight connector to meet NASCAR ignition wiring rule 20-6.1, with individually sealed pin connections that keep out dirt and moisture. All primary wiring meets MIL-86A specifications with tinned conductors for superior crimps, and the multiple-sparking CD circuits are encased in a clear two-part silicone elastomer inside the cast aluminum housing for vibration protection, with a clear base plate for easy tech inspection. A built-in Soft Touch Rev Control, adjustable with plug-in RPM modules, protects the engine from over-rev damage caused by a missed shift or driveline failure.
