65 Dart Wagon Conversion to a Sedan Delivery

Looks like I lost everything concerning my issues with the HVAC controller in the server crash.

The issue basically Boiled down to the NOS controller (which I had determined was for 68-72 and not 60-76 as advertised when I bought it years ago) being different electrically-speaking different from the 3 old 65/66 broken controllers still attached to the hoses from the units I had bought. You can see the difference in the terminals here. Tge 65/66 controller is the white one, black one is the nee one.

the 65 AC supplement I have was sort of a help; I was hoping the 69/71 FSMs i had would show where all the terminals went. Yes BINGO! Additionally, it showed the same components as was shown in the 65 supplement

With both sets of wiring diagrams I was able to construct a new wiring harness to join all the components to the terminals on the controller. The main difference it seened was one of the terminals was routed a bit different to one of the components and the other two went to the fuse panel. 5 hours of work went into this harness. I needed to lengthen the wire going to the compresser and will likely need to lengthen the wire to the blower motor. I will do that at a later date when it’s all installed.

One thing I noticed was the firewall grommet from the original wiring (and from the firewall grommet for the vacuum hoses) Were routed in from the nice flat side leaving this ugly looking knob inside the engine compartment.

This meant the wires/hoses were routed threw the grommet and was installed from the insidei. I decided to install the grommets where seen in the engine compartment where they looked good.

Grommet for the hoses to the water valve and vacuum fitting on the intake

And the grommet fior the wires going to the blower motor and compressor. It might be wrong byt thats OK by neView attachment 1715790125
Dartman, what size is that hole in the firewall for the grommet, and do you have any extras?
