Wiring schematic for 2012 318D

[Corby8867]

My momentary switch that operates aux hydraulics is not getting power and neither solenoids are charging and I have no pressure at the aux connectors. These machines are horrible to work on since you have to raise the cab then can't diagnose power issues or use a meter without having a remote run and start box. Any ideas what I should look for? I am getting aux error codes. Regardless....I'm doing a diagnostics check and they show no voltage going or coming to proportional switch/momentary switch. Any ideas
