AC WIRING HARNESS CONNECTIVITY HELP

[lemontwis]

I Have a 1970 Cuda with factory AC; However, the AC wiring harness was gone at purchase. So I got a Factory E Body Cuda AC wiring harness and most connectivity is plug and play. But the end of the harness at the resistor hookup end has a DGRN and a Light green 2 connector plug. Looked a wiring diagrams and can't figure where these goes for connection to main harness?

Can anyone help me please?

Here's some pictures of my original harness connected to the AC/heater switch and the terminals that go to the AC/Heater blower motor resistor. I'll try to look further next chance I get.

thank you 71RT383 ,the 2 wire tan piggys of the 1 wire tan wire. Must be for defrost.

Hey Dave,

I see what is the issue. This first picture is a normal non a/c wiring setup. The dash harness has an insertion wiring connection between C1-14BK* and C1A-14BK*.

View attachment 42196

For the A/C wiring, disconnect C1-14BK* and C1A-14BK*. The A/C sub harness dual tan connector C7-14T and C7A-14T plugs into C1A-14BK*.

View attachment 42197

Further away from the A/C controls, there is the CIC-14BK* on the A/C sub harness that plugs into C1-14BK*

I edited the schematics to show where these connections are.

Hope that helps.

Here is the "mystery cable" connector (light green and dark green)

that is at the end of the AC Harness just before the BLOWER RESISTOR Plugs, it comes off the harness about 8 inches from that end resistor plug into the AC box at the passengers feet area.
Please help!! What does this connect to?.....

The pictured air conditioning (AC) sub-harness two-terminal connector with light green and dark green wires connects to the main harness wiring from the blower switch.

The connection is shown in the highlighted diagram in post #2, but is also shown in the specific AC electrical control diagram in the following image:

The following image shows the two terminal connector mate for the AC sub harness blower resistor connection from the main harness:

The following image shows the wiring branch from the main harness to that connector:

The following image shows the blower switch end of that wiring:

On a non-AC car, the two terminal connector from the main harness connects directly to the standard heater blower resistor block. In an AC car, the AC sub harness connects to this main harness two terminal connection instead, and then connects to the different AC/heater blower resistor block.

Appreciate this info...So as I read this can I say that this connector is unused on an AC Car and I can just tuck it away under dash?
