Andrew,

Unlike the Delco Alternator, the Lucas Alternator only has +12V outputs (the 3/8" spade connectors) plus the 1/4" connector for the ignition light.  The outputs are identical.

Every JH wiring harness I've seen is slightly different, so I couldn't tell you exactly which wire goes where.  However, I assume you're replacing another Lucas alternator?  If so, it doesn't matter if you flip-flop the 3/8" terminals.

Of special note...The Delco Alternator has 3/8" ground connector.  If you are replacing a Delco Alternator with a Lucas unit YOU WILL BLOW SOMETHING UP if you attach the GND wire to the +12V terminal!

Just remember the story about the "Lucas Smoke" on Ebay...
