Wiring 4 wire alternator with external voltage regulator with Dakota dash and painless wiring harness

1971 mustang coupe 302 alternator wiring
I need some help folks. I for the life of me cannot figure why the brand new alternator and voltage regulator will not charge. I have the Dakota digital dash and painless harness installed. I’m working on it after someone else installed it all so I didn’t start from scratch. I need to figure out how to make the 4 wire alternator with external regulator work. What wires go where and all that. Thanks for your input.

How is the regulator wired at the moment? Are you using the factory harness? The Painless harness throws a wrench into the works, but it can be handled.

I don’t not have the factory harness. I have the pigtail/plug for the regulator. It’s pretty much not wired up now so I’m at square one now. I have a wire to all 4 terminals of the alternator(batt, ground, field, stator) I just don’t know where to run those and or the 4 wires of the regulator.
