http://67-72chevytrucks.com/vboard/s...5&postcount=20 shows how to wire up an internally regulated alternator. The ammeter (battery gauge) connections stay the same as they were with an externally regulated alternator.
The black wire on his diagram (the one that's connected to the junction block near the battery) should lead to pin #12 on the cluster connector. And the black wire with white stripe (that's connected to the power distribution splice) should lead to pin #1 on the cluster connector. Accidentally getting the #1 & #12 connections reversed won't do any harm but it will cause the battery gauge to read backwards (showing charge instead of discharge and vice versa).
