Horn and windscreen washer wiring

[Max911]

Hello everybody

My 911 T when disassembled had a mess in wiring (added connection) but horn and washer windscreen were missing...

Could you help me telling which is the number of fuse in fusebox where to source them?

Considering that wiper switch is ok I think I have only to catch + wiring in fusebox...

I think it's the same for horn, although it operates via rele' from a - wiring on wheel, isn't it?

Thanks in advance
Max
