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.
