CQ with AAN swap unconnected connector identification help

[khai_tuan_nguyen]

Hi guys,

I have a 1990 Audi CQ with an AAN swap. It has a S2 engine harness. I have a bunch of connectors that are not connected to anything and was hoping someone would have an idea what they are for.

I am not sure if the connectors are from the S2 harness or a different part of the factory CQ system.

Here we go

Coming out of the driver side area of the firewall:
2 pin connector Y/Br & Br
2 pin conenctor Br/Blk & Br/Blu

Coming out of the same bundle that the headlight connectors come from on the driver side:
2 pin connecot Br/Blk & Br/Blu (Weird that this is the same color as the wires above, maybe this wire or the one above is faded and it was original purple or something, but it looks blue to me)
2 pin connector Br/Wht & Br
2 pin connector Br/Y & Br/Blk
Conenctor cut off, single thicker wire Green/Y

Comes from driver side, but runs along firewall to passenger side:
1 pin exposed blade connector thicker Blk wire
1 pin connector Bl/Wht that connects to another round Blue/Pink connector along firewall
2 pin Br/R & Wht/R

The Whts could also be faded grey or violet as well.

Any help or idenfication would be greatly appreciated.

the single thicker green wire if i remember correctly is aircon.

the single thicker green wire if i remember correctly is aircon.

Do you know what it connects to? Compressor? Condensor?

Thanks,

Here are some pictures. I wrapped the connectors with electrical tape and bundled them so it may be a little hard to tell.

Conenctor cut off, single thicker wire Green/Y (Was told this might be aircon system, but would like confirmation and to know where exactly it connects to, compressor, condensor?)

Comes from driver side, but runs along firewall to passenger side:
1 pin exposed blade connector thicker Blk wire (I think this is for the lambda probe since I am running wideband straight to VEMS, but would like confirmation)
2 pin Br/R & Wht/R (I think this is for the lambda probe since I am running wideband straight to VEMS, but would like confirmation)

1 pin connector Bl/Wht that connects to another round Blue/Pink connector along firewall. Picture is of the round blue/pink intermediate connector.
