1972 vs 1973 Dash Wiring Harness

I have already cut the firewall patch out of the '73 and welded it in the '72 so the physical installation of the '73 AC/heater box is already handled. The schematics show that the firewall plug pinout is exactly the same between the years.

Thanks but I have the harness out of the '73 but I won't use 50 year old harnesses. I waffled on this with my Coronet until I started using some of the 50 year old harnesses and the blower motor switch connector got so hot I could not tough it because of the high resistance due to the years of corrosion in the factory crimp. If I had the energy to remove every connector and find every splice and solder them maybe but with as much money I am putting into the restoration a $400 harness is worth it.
