washer fluid level switch harness
 

Question is for Audi A4 2007 (B7) that in stock doesn't have trip computer and thus washer fluid warning option.

Can enyone tell me where does red/brown wire from pin #1 in the 32 pin blue connector of the instrument cluster goes (I didn't see it round the reservoir).
I was searching the ELSA in the current flow charts by the keyword "instrument cluster" and didn't found anything. All I was able to find for the "instrument cluster" was in a service manual where I found pin descriptions for both blue and green connectors.

As you can see I am retrofiting the trip computer on my car and would aslo like to enable washer level switch rather than just ground pin #1.

I appreciate the help. I still have the light on, but I'm planning on taking the car in as soon as I can to get it fixed. There is still no difference in the coolant or washer fluid level, which is good.
