I'm hoping the photo attached of the contents in our first compartment on the driver's side. In the upper right corner there are two block connectors. red arrow is pointing to them.
On our coach:
Front is yellow-purple (r/f) yellow-green (l/f) black
rear is yellow-blue (r/r) yellow-red (l/r) black
Sometimes unplugging and reconnecting is enough to reset.
Or to raise an individual jack, use jumper wires to connect the yellow wire to ground and other colored wire in the set to 12 volts. [note red and black location for 12v on left wall of compartment]
to lower individual jack, use jumper wire to connect the yellow wire to 12 volts and the other colored wire to ground.
