Newer Kohler K321 in an older 140H3

I just picked up a strong running Kohler K321 from a JD 212 which was upgraded. Everything is going well with the conversion other than the old 140 has a voltage regulator on the frame, and the newer motor has one on the shroud with extra wires coming from the stator.
I want to continue with the new system, but I am unsure of what I will need to change in the wiring. Basically I want to remove the old regulator and use the new one, but I will have the woring harness from the old one to deal with and am unsure of what to do with them.
The wiring on the tractor already needs some repairs and such and with breaking my puller trying to pull the flywheel to change the stator and flywheel to match the existing wiring, it made it easier to stick with the new charging system already attached on the motor itself.
Can anyone offer any suggestions or help as to how to convert my wiring to accomodate the change?
Thanks !
 
If memory serves me correctly, the center terminal on the new style regulator is the output. I can't say for sure, but I think it may need to go through the ign switch. Seems like it will stay active and run the battery down if you don't.
 
So that one would be the "B" terminal on the new regulator?
I should just eliminate the old wiring connecting to the old regulator, and add a wire back to the switch?
 
yes,on that system you just hook the B wire to the pos battery and she will charge.I think i would want the B wire to be hot only when the key is on .
