1998 300tdi 130HCPU aftermarket aircon not working?

[Wills130]

Hey guys,
Now im in school holidays i’ve decided to have a tinker and figure out why the aircon is not working because it was when we got the car (roughly september 2022) and i would like to drive in summer without dying.
When I took apart the lower passenger side of the dash there was a connector that appeared to lead to the airconditioning fan thing at the bottom left of the unit:
188220
The main question is where does that bottom wire highlighted go?
Imve checked the fuses under the passenger seat and they all seem fine with good connections.
What else do i need to check in order to get it working?
There are also loose cables in the aircon unit that appear to match but not sure how they got to where they are?

What exactly is not working?

The cooling or the whole thing?

The whole thing is not working, i think it is fuse related now having spoken to my dad, he says it was working until we messed about fixing the radio so fairly sure we’ve blown a fuse or something.
I guess the main thing i’m asking for is a guide of where to find certain fuses related to this aircon unit.

If it's the same as the dealer fitted AC in my 95 130, the fuses are on the back wall of the battery compartment under the passenger seat, as is the control module/ relay thingy.

I have a photo of mine, but I can't for the life of get it to upload.

The main control wire is white and comes from the back of the cigarette lighter, may have got disturbed.
