New A/C-Heater harness question? (70 Charger.)

[b5blue]

I'm replacing my dash harness soon:    https://www.yearone.com/Product/1966-74-a-b-e-body/hu272b   
I see an A/C-Heater harness listed also:    https://www.yearone.com/Product/1966-74-a-b-e-body/l38447/CrossSell
  Is this for "just A/C-Heater" or fine for a car with just a heater also? The reason I ask is I'm setting my harness up for Classic Auto Air's kit that converts a heater only B Body to A/C-Heat. The kit adapts factory heater controls to run the A/C and heater system so I want the correct "starting point" to adapt to with the kit.

Neal you can download the installation manual from Classic's website.  If I recall, the kit comes with everything, electrical included, to swap the stock heater system to A/C so I 'think' you won't have a need for the A/C harness.  Double check though, I have been known to be wrong...from time to time.
