I started looking at the existing wiring and the manifold heater is connected to the voltage regulator below the dash. With a 3 wire I don't need the voltage regulator but does the manifold heater need it? If I remove the external voltage regulator, how should i connect up the manifold heater?
Also, if I replace the key switch, don't I have to connect that to the manifold heater? I have a new key switch but it is different than the old one.
By the way, my manifold heater doesn't work. I think it is because the last guy decided to rewire with the 12SI alternator and didn't hook up the manifold heater correctly.

Your manifold heater gets power from the relay/solenoid between the back of the engine and your steering pedestal. Your positive battery cable should hook to one side of it on its way to the starter. The small wire from your switch is only the trigger wire to that relay to make it work. You could jump 12 volts from any where to that solenoid to see if the heater works.

OK. Thanks. I will try to debug that manifold heater and get it to work in this rewiring process.

Steve in NJ, didn't see your post until now. Good news is that I wired things up as you indicated about 4 hours ago and I have everything working.
Getting 14 volts from the alternator. Multimeter is showing 14 volts at the battery with engine running at 2000rpms. Voltmeter is showing 14 volts too. So I am now charging my batteries. Ironically, I don't think my alternator has been working for a year or more. I put battery charger on over winter so that probably kept them going.
Steve in ill thanks for your diagrams and help!
Now going to have to figure out the manifold heater. My Wilson 3 wire 12si is 83 amps and I reused my pulley since it lined up with my belt. I will try my lights to see the difference tomorrow.
Thanks to all that have helped me be an amateur electrician!
