So I have been working on my project 70 dart little bit. I realized a small leak from water pump so since there pretty cheap I went ahead and ordered a new one. So when taking everything apart I realized the previous owner just had the alternator mounted on there and had the belt on it but I have no wires connecting to it. I've seen wiring diagrams but I'm a newbie at this and it just confuses me lol. Can anyone please explain how I go about wiring up the alternator? Thanks

Are you using a 70 type alternator, or some aftermarket "one wire" or what? Is the harness chopped up? It should just "hook up.
Originally a large no10 charging wire with eyelet hooked to output stud. There should be a blue and a green both with separate "push on" flat spade connectors. Those go to the two field connections. Does not matter which where. The regulator has a triangular shaped connector. It MUST be well grounded
Simplified diagram:
Start with the alternator:
Top BATT is black with eyelet goes through firewall to ammeter circuit. That should be there
Green field ends up right at alternator, goes to regulator F connection at the regulator connector
Blue field is fed from ignition switch "run" voltage. That same circuit branches off up near the ballast resistor and feeds the regulator "I" terminal (I for ignition)

It is a 70 style alternator. It has labeled on back of it one terminal for battery and 2 for fields. I will look later when I'm off work but I don't remember seeing any wires laying around near it. So I should follow the blue and green wire that goes into the voltage regulator and see where they go?
I traced the blue and green wire from regulator and found the missing wires! It was hanging down behind the motor. This is what I found, I see the black wire for battery and blue and green wire for fields, but what the heck is the brown wire for? (The wire I'm holding) is that the temp sender wire 67dart273 mentioned?
That one in your hand is the Temp Sending wire and is/was Violet.
