Papa's Retirement Type 65 Coupe Build - Index in first post

[Papa]

I started laying out the heater and A/C wiring today. I started with the connections that go to the control panel and then worked from there through the other legs of the provided harness.



I ended up needing to extend the leg with the plugs that go to the evaporator by about a foot. I'll be running this leg from under the dash into the passenger footbox and up to the evaporator.



Next up was the heater control valve. It looks like I'll be routing this set of connections inside the footbox as well, which means that the remaining parts of the harness will be coming out of the front of the footbox with a grommet. I'll also need to decide how to handle the extra length of the wires with the plug that goes into the heater control valve.





The rest of the connections on this leg of the harness are for the trinary switch and the compressor. The remaining leg is the power, ground, and fan. I'll tie the power into the heater wire from the RF harness and run the ground to a convenient location. I need to read up on the fan wire, which doesn't show up on the Factory Five wire diagram. I also have the fan thermo control wire from the sending unit harness that I kept that will go to the trinary switch.



Making steady progress with the wiring!
