No power to airmatic compressor, tested cables, replaced fuses and relay, rebuild junction fuse box in passenger floor board, and also tested valve block level actuator sensor. This was the only way i could get power to the compressor. I have also followed wiring from compressor to passenger SAM Module (fuse box) and still no current flowing through wires. Im stumped. Anything else i can check? Comments appreciated!

Update: Ended up converting to coil conversion. Customer could not maintain let alone understand an airmatic system. I probably could have ran a switch to supply power to turn on and off the compressor but i would also have needed a way to monitor the quantity/lbs/bar of air in each strut and that would have been too complicated for the owner to use lol. But this is just a video clip of what i did to test the compressor since i wasnt getting power to the connector and neither replacing fuse and relay or new compressor did not solve issue.
