The sense wire needs to be hooked up to battery voltage, usually at a hot central connection that you want to maintain @ 13.6V. I’ve seen many where they just run a wire from that terminal to the Batt lug on the starter. The other pin is not needed, or is mainly used to run the idiot light that tells you when the alternator is not charging. 

Peace,
Pat

  My question is, do I need the extra 2 wires, a "sensing" wire and ?  Can I wire the output to the original output to keep the Amp meter working, or should it go straight to the battery?

  This is all under the hood of a 1968 1600.

I promise, this will be my last alternator question!

  I remember reading somewhere, that the Datsun gauges were just idiot
lights with hands?

  So now I need to figure out where the charge idiot light is on the dash.

Thanks,

Paul

I ran the idiot light wire to a bulb I mounted below the dash. It has to be=
