Yes I am just full of questions

Did the swap , very happy with it except at idle it dips to about 12.5 v , I notice the pulley is bigger on the 3G . if I swap my fox pulley do we feel it would help ?

4ga wiring from alt to Solonoid with fuse as well

is it the 1 wire version with internalregulator? Those require a bit of rpms to get them "started"
no sir has the same connections as reg 3 g the reg is on the back 3 wires

the white goes from the big connector to the small square one , green to green yellow to yellow and then my 4ga

Yes, swap the pulley.

You'll need a 5/8 ID washer to act as a spacer. You'll see what I mean when you try to slip the 2G pulled onto the shaft.

I thought so as well but I had it tested its fine. Its internal. I'm just thinking its cause my underdrive pulley

yep. ditch the U/D alt pulley as it's probably 2 1/2" and is meant to slow the alt- not good. . I bought the March overdrive pulley off Flea bay.. Sorry don't remember the PN off hand but it made a big difference. You can see it in my sig pic.
