Installing one wire alternator

I think the term shunt in the instructions is misleading.

Basically what you are doing is bypassing the ammeter.

You still need all the existing OEM wiring hooked up as it was originally. (Except the voltage regulator and field related wires)

The benefit to doing this is now the loads of the car (main splice, etc) are shared by two spade connectors thru the bulkhead connector vs just 1.

Okay I'm not there yet but yes, I'll be removing the external voltage regulator/plug. The green wire that goes from the plug to the ALT is easy, the red wire from plug goes into the big splice. I assume I can just cut that at the splice? (Then that little harness will be free)

Going back to my original question, I will have the ammeter reconfigured to a voltmeter. But is it still good to run the original black 10ga wire to the ALT output stud as well?
