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 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.
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 or ignition based tachometers, only a stator signal tachometer. (tach shown is not included)
This link is to a tach that works, there are many versions on the market and this is not an endorsement just showing what specs you need.

Very happy with my purchase work great has fixed my problem I have been having with my truck since I got it
Ordered for my 91 dodge diesel that has always had charging problems, eating thru voltage regulators, pulsating headlights, overcharging everything. Ordered this, showed up in a week, took 20 min to install and INSTANTLY fixed every problem the truck had. Great product, worth every penny. Couldn't be happier.
Took me less than 20 minutes to install. Works great , fixed my fluxuating dc voltage issue.
I have 91 dodge with Cummins I put about 14 external regulators on it in last 5 years every time had some where to be in a hurry it would go out. Found this from Pa performance put it on battery gage works correctly was very easy to install. And my head lights don't flicker the way they did with factory setup I'm very happy with it so far I'll leave follow up again after a few months in service
