Odd/basic question about AWD Pressure sensor

[percavman]

Alright, so I am replacing the AOC pressure/temp sensor on my XC90 and I want to make sure I put it in correctly. There is a convex/concave washer and a seal/gasket. Does the seal go between the washer and the DEM or the washer and the sensor? Also, which way do I put the washer, convex side towards the sensor or DEM?

Thanks in advance!
