All or nothing alternator conversion

That alternator is wired exactly the same as a 1970-80's Mopar "square-back". Many posts on here. Post 9 is correct if using the 1970's triangle-connector Vreg. You can even use it with your original square Vreg. You simply ground 1 field terminal (either one) and run the "fld" wire to the other field terminal, again same as for a square-back. And you can buy an electronic version of the 1960's Vreg w/ same wiring and look. Advantage is no change to existing wire harness.

Going further, the later "round connector" alternators (like my 1996 Voyager) are the same w/ just a different connector (90 A or 120 A if AC), though common "57 terminal" (spades) will fit. They later changed to an oval Metri-pak type connector (like my 2002 T&C), but still 2 field terminals and external Vreg. In the 1990's, they moved the Vreg into the engine's PCM. When that circuit fails, a shop would change your PCM at $$$, but many smart truck guys just intercept the low-side field wire (other one is just +12 V IGN) and wire in an old 1970's Vreg. Get 'er done spirit.
