Removed original voltage regulator and now it wont start

I 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.

The dark blue is "ignition run." It comes from the ignition switch, out into the engine bay through the bulkhead connector, and at some point branches off to feed the ignition ballast resistor and the VR "IGN" terminal. I don't think the older cars feed anything else. Somehow, you have screwed up your ignition wiring doing so.

The ignition resistor should have a brown and blue at one end. The brown is the bypass circuit "IGN2" and is hot in "start." It feeds the coil directly when starting. The other end should have at least one and maybe two dark blue. It is hot in "run."
