RECENTLY ADDED FEATURE
We have added an optional W-Terminal or TACH pickup wire to this alternator. This option is only available on these “SE” Denso / dodge alternators that eliminate the PCM. When you select this option we will provide a single stator/tach lead for connection to a diesel specific aftermarket tach. This is only available at the time of assembly and older units are not physically eligible for retrofit. We have successfully tested this on various models of tachometers that allow for stator input. The connection is simple, the wire is provided by us but does not need to be used if no tach is intended. This will not work with factory equipped tachometers. (tach shown is not included)

Forget about tracking down bad temp sensors or bypassing the PCM with hit-or-miss external regulators. With it's super simple installation and rock solid 14.7 charging volts, this alternator will make your 12 valve Cummins one step closer to "Wasteland Ready"!
