internal regulator

[J kippin]

So I am installing a new alternator in my truck. I have searched the threads on this and I am unsure if I need to add a resister or not. I have a stock gauge package in my truck.
I have already cut back and removed the old wires and regulator from the old harness.
The Blue wire is hooked to the brown going to the alternator.
The Red wire that went to the external regulator was left, I just put a splice connector on the end for possible future use.
The Black is sill going to chassis ground.

So at the new alternator,
Blue going to the alternator to the #1 terminal
Red jumper coming from out put side to #2 terminal
Original Red on the output.

So back to my original question...Do I need a resistor installed to make this work correctly?
