I assume you bought the 3G alternator pigtail when you got the alternator.
The easiest solution for you is to remove the old 1G regulator.
With the engine off and the key on, find the wire that has 12 volts.
Connect that wire to the "I" terminal on the 3G.
Tape over any of the original wires that were going to the 1G regulator, except for the one mentioned above.
Connect a minimum 4 gauge cable from the alternator to the starter solenoid on the same post as the battery lead. Reference the drawing of the alternator in my earlier post.
Start the engine and with a volt meter, place a lead on the starter solenoid lug that is connected to the alternator. Ground the other lead and look at the volt meter, you should see between 14.3 and 14.7 volts
