Mike,if your gonna go to the extent I did then just get rid of the old ext. voltage reg. wiring.

The only wires you will need are the ones comeing from the #1 and #2 terminal(white and blue wires).All the other wires going to the extenal voltage reg. can be eliminated.

The red wire that goes into the plastic bulkhead connecor at the firewall feeds power to the fuse block under the dash.

Now the brown wire that's in the ext. voltage wireing.You'll need to retain that as well.
1st question is do you have a full gauge dash or is it just idiot lights?

I ask as the idiot light dash utilizes a bulb that is the ALT/GEN. warning light.
The full gauge dash does not have that bulb,that's what the amp gauge is for.
Here's how MAD says to wire it up.
