converting to guages

I am getting rid of the old warning light dash and adding a guage cluster. This truck i think has an internal regulator alt. on it so if any of u know what wire to run to the #1 pin in the dash harnes please shed some light ( it calls for me to tie into 12r from the voltage regulator)

Update. it dose have a exturnal voltage regulator, could the 12r stand for a 12 guage red wire?
