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.

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*.

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*.

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.
