67 dodge charger wiring help needed.
 

My buddy passed away last July and his wife has asked me to help get his cars ready to be sold. My biggest challenge is the 67 Dodge Charger. It is about 80% finished but I am having trouble with the wiring to the A/C heater control panel. I can't find a diagram that shows what wires go where.
Can anyone here help me? I have the dash wired but the A/C controls are stumping me.
I don't have any pictures right now but can get some tomorrow.

Just to let Y'all know I no longer need any help with the 67 Charger. A guy came by to look at it and bought it on the spot! Not only that, he also bought the 1957 Belair convertible restomod and the 1963 Corvette roadster! while I didn't get any responses I know if anyone here could have helped, they would have.
