Rallye Dash Demons -Help-

I am in the process of converting a /6 to 340 Demon. I am trying to get this right now, instead of having wiring demons in my Demon later.

I have already installed the metal frame of a 71 rallye dash in my car. The car still has the non-rallye dash harness with a/c. I have a rallye dash harness (year unknown) and doesn't appear to be for an a/c car. The bezel is out of a 67 Barracuda with a/c. I am grinding off the 67 flasher hole in the upper left of the front of the bezel and covering it with the woodgrain panel from a 71.

On the back of the rallye dash there are two plugs, one circular 13 pin with two empty. There is also a three pin connector off to the right.

Anyone know what the three pins plug goes to (green, orange, red)?

Does anyone have the color codes for the wires?or might be able to email a color coded schematic or diagram for a 340 rallye dash?

What does it take to add the a/c wires to the rallye harness, or should I just use the non-rallye harness and try to cut it up?

Do I need to change any of the under hood wiring if I change out the non-rallye harness under the dash?

Does anyone have the actual part number for the Rallye Dash with a/c harness?

I have checked with PainlessPerformance but I already have both harnesses and instead of spending more money on this, I just need some wiring help. Thanks for any advice you might have!
