Removed original voltage regulator and now it wont start

I don't know what diagram you followed but a basic '65 Dart generally has no extraneous wires, at least for street use.
Also '60 amp' rated alternator is not original but knowing that may or may not be important.
What are you trying to accomplish?

Pishta is correct. Higher output alternator is generally not going to put out any more current than a stock unit - except if the battery has been drained down. IIRC '65 a-bodies have a robust pair of connectors for the main feeds, so that and the ammeter run should not be a problem - again depending on what you're doing.
Not sure why Brian posted a diagram that looks like its for Aussie Valiants. But the concept is pretty similar.

I followed the darts wiring diagram so i could see which wires were originally used to hook up the alternator since my new one i have hooked up using the 1-wire system and have it connected to the battery, my long term plan is to upgrade my wiring harness since i plan to add an electric fan and a few other accessories. My issue that one of the alternators wires connectes to the external regulator on the fld side and when i disconnected it still turned over but when i disconnected the dark blue ignition wire it wont turn on, those alternator wires and dark blue ignition wire are the only ones i have taken off/disconnected.
