    Default converting an external regulator to a internal

    Does anyone have a diagram of how to wire a 1971 gs 455 from an external regulator to an alternator with a internal one? I have instructions but without seeing a drawing I am easily confused. The alternator was on the car and the regulator is gone off the firewall. I assume its an internal one, is there an easy way to find out?
    Thank-you,

    Thats the instructions I currently have but I am stuck on number 3 of the installation. Is there two red wires attached to the rear Bat ring post and is one of them going to the battery?

    This isn't hard. You need to change the molded plastic connector that plugs into the alternator (about $6 from NAPA or any other real parts store); and install two homemade jumper wires into the plastic connector that USED to plug into the external voltage regulator.

    The older external-regulator alternator has the connector blades for the indicator and field connections on the rear, and they are side-by-side like this: II instead of side-by side "inline" like the internal-regulator alternator: _ _
