Need More Amps

[jjstang69]

I'm looking to trash my current 65A/Ext. regulated altenator on my '82 GT for a 3G 130A Alt. Can anyone point me in the direction on how to do the conversion? I'm needing help wih the electrical conversion e.g. externally regulated to internally regulated and such. The hardware aspect isn't really a concern as I understand the fitment corrections. I've seen workups for the '87 up cars, seems like a no brainer. I just haven't found any info what I'm looking to do as of yet. All insight, thoughts, and suggestions will be greatly appreciated.

How to wire a 3G in an 85 or earlier Mustang
cut and paste from an old post of mine...

There are 4 wires to the voltage regulator, cut the plug off the regulator, extend the 2 wires used to the alt and cap off the other 2

The F will not be used.
The I will not be used.
The S will go to the 3G
The A will go to the 3G

wiring on the 3g side

The Big post on the back goes to the solenoid, same side as the battery, a fuse is recommended on this wire, also up the wire size to 4ga minimum

Now for the 3 wire plug...wires A,S,I

A goes to A from the old external regulator
S goes to the stator connector on the 3G
I goes to S from the old external regulator

Thank you very much. That's what i needed. Here's to bein able to sit at a light and not watching my volt meter float around 10 volts with just factory accessories running.
