internal regulator alternator ?

[twoskies]

Good Evening

1972 C10

got a couple questions about wiring for an internal voltage alternator, ive already got the alternator, it is on the passenger side as opposed to the original drivers side(79 el camino complete motor)

heres the question

ive seen 2 different ways to wire from the 4 pin clip to the original regulator
1st way is to jumper or splice the 1 and 4 wires ( brown and blue) together and run the blue wire to the #1 on the alternator, then to connect the red wire #2 off the clip to the #2 on the alternator with a new wire

the original red wire that attached to the battery post on the alternator still goes to the same in both scenarios

2nd way ive seen is to run a jumper on the clip to the brown and the white(#1 to #3)and jumper the red wire to the blue wire (#2 to #4)
and then run the white\brown wire to term #1 on the alternator and run the blue\red wire to term #2 on the alternator

i do have a guage dash, not lights if thats a concern

which is the best way ?

just dont want to burn anything up

appreciate the responses

Thanks
