I have done the alternator wiring thing this way since they first came out.

10 GA wire from the starter, where the battery cable attaches, to the power lug on the alternator.
The regulator plug has two wires on it, one 12 ga, and one 16 or 18 ga.
Run the 12 ga wire from this plug to the power lug on the alternator that the main power goes.
The remaining smaller wire can either be cut, or it can be run to an idiot light.
If you use the idiot light, it must be a two terminal socket. One wire runs to the fuse panel, to a switched fuse. The other is connected to the small wire from the alternator.
The double terminal light does two things, it lets you know when the alternator is charging, by going out, and it keeps the electrical current from returning to the system and keeping the vehicle running after the key is shut off.
Like I said earlier, this has worked for me for years, and I have NEVER had a problem.
