Clarification on 70+ alternator VR on 68 cuda

The alternator should have 2 field terminals. In that case, You'll add a branch to the blue wire. The original connector that you'll cut off at the regulator is the one needed at the alternator so all you need is about 8 feet of blue wire, butt connectors, and hardware to mount the regulator. It doesn't mount to the same holes. It does need to be well grounded at its mounting. I added a hole and a spacer about 1/2 tall to keep the reg' in the same location. I disconnected the senders, coil, etc.., to lift the engine harness, unwrap, and add the blue wire in.
Now with a square back alternator that has only 1 field terminal, I guess you wouldn't need to add the blue wire? Just make sure the alternator is well grounded through its mounting brackets? But then you wouldn't have the isolated field like late model OEM. Your upgrade is solid state regulator and higher output alternator. I honestly don't know how much difference the isolated field makes. I did use the proper alternator and wiring for complete upgrade. I figure if I go ahead and do the same way their engineers did, I don't need to question or understand all of it.
