Wiring question: thermal swith and brown/black wire

[julahti]

Two questions:

1. Am I right if I connect thermal switch so that there are
a) yellow wire from solenoid and
b) red/black wire going to CSV. The second wire at CSV is also yellow, does it come from the thermal switch (so that both yellow wires are in the same connector at thermal switch) ?

2. Air flow sensor has a brown/black wire and a brown wire. Right? Where is the brown/black wire going to?
