Going from pre-70s V Reg to the newer post-70s V Reg Squareback

Ok I know this has been explained many times on this site. And I've even tried it on a few different alternators as I was swapping from Points to Electronic ignition.

So I just need clear instructions on my current setup:
1. I have electronic ignition installed (junkyard HEI setup) and working
2. I have a OEM Chrysler Squareback alternator, which replaced my old roundback. It is working and I have grounded the 2nd terminal to the alt case as required.
3. I have installed the newer electronic voltage reg (blue one, that I sanded the blue paint off)
4. I have a ground wire directly connected to each item in the HEI set up, ending at the battery neg.
5. I have installed a relay for the ignition wire.

With this setup, I am running pretty good, voltage bounces around 13.9 - 14.4 at low idle. And stays 14.3 - 14.4 when driving at normal speed. Overall the headlights (all lights, cluster, dome etc...) have a quick flutter. More noticeable at idle than when driving.

So for ***** and giggles I want to try the later voltage regulator , the one that has the triangle plug. Just to see if it has any effect on lights or voltage fluctuations.
I have this one picture, but what I need to know, on this Squareback alt, I took a small wire and grounded the 2nd terminal to the case. Do I undo that? and run that wire to the newer Volt reg.?
Thanks for any help.pic3.gif
