they are the same, i wanted to see if the pump was running, i have seen a few where the black cube relay on top of the hydraulic pump will fail, when that happens it sends the unit in to a failsafe up mode where roll bar is deployed, it usually will not lower until power is restored to the pump system

...and according to the service department, the relay and pump are a single unit, so BOTH get replaced if there is a failure!

Set me back $2100 in parts and labor!
