white blk wire will be shorted to the white red wire
yellow short to the white wire.
ps if you have a electric chooke your battery will die as its will be engaged so hopefully you have a manual choke.since you have a 72 if will be elelctric choke if you havent already put a manual weber carb on there. Or a weber with a electric choke.

I just did this in my 77 620. Im not sure what the yellow to white does other than the choke, but w/k to w/r did some magic. And theres definitely a relay clackin when I hook yellow to white.

That will be the choke heater. With the key off, although there is no power to the choke the relay coil IS syill powered and will drain the battery over a day and a half.
What I did was find and unplug the relay.
Find the RED idle cut solenoid wire and splice the BLUE choke heater wire into it. Now the choke gets it's power from the idle cut solenoid source which is on when the ignition is on.
The RED wire goes to the hex sided idle cut solenoid. The other wire is BLUE under the black plastic cover.
Join the Blue to the Red and you are good to go.

So what your sayin is...if I was to install a factory 79 IR alt in my 75 620,... cut the pigtail off the volt. reg and connect the w/r to the w/b and the y to the w, the 2 left over wires would not be used, plug the shorted pigtail back into the harness, and connect the blue and red wires of the three that connect to the factory carb( im running su's) thus keeping the relay from running all the time Im good to go?

Close. If running SUs you don't have an electric choke so you don't need to join the Red and Blue wires. Be sure to unplug the choke heater relay so it doesn't drain you battery over the weekend.

choke heater relay, located on the pas fender yes? the trucks pretty much gutted of alot of that allready so unless its somewhere else i think i got it disconnected but now im starting to wonder if the choke heater relay is not were i think. feel like helpin again? thanks.. all other wiring sounds right though?

My problem is that the battery is draining. With the motor running the battery is showing almost 15 volts, and 12 with the motor off.

Well the alternator plug that I used to join the wires, I removed all the others so there wouldn't be any possibility of one touching anything else.
Choke relay must be unplugged at the right fender. It's the plug with the...
Well I have no faith in today's re-manufactured crap. Very often they are 'bad in the box'. Take the plastic plug out of the back of the alternator and see if that removes the draw.
If no, I can't see what would cause this related to what you've done. So... remove each fuse one at a time till you find which circuit the draw is on.

put a test light on battery in series .The light should come on if there is a draw. now lift a fuses and see what circut it is then work from there disconnecting whats on that circut then when light goes out then the draw stopped
