Step 10
Install breather cap on power unit and connect hydraulic hose from power unit to flow
control. Remove tack weld from Step 4. See figures 9 thru 12 for hose and battery
cable connections.
On Gravity Down liftgates, install return line in place of plugs
on butt end of cylinder and return port on pump reservoir. On Power Down
liftgates, the rod end port on cylinder must be plumbed to C1 port on pump.
(note: Incorrectly plumbing rod end port on cylinder to C2 port will make gate drift
down and motor to spin backwards from raised position.) Attach ground cable to the
tapped hole in the pump base labeled “GnD” and to the trunnion mounting plate with
the .38 hardware and internal lockwashers provided.
Step 11
Locate and mount the toggle switch assembly or pushbutton box in a convenient
place and wire the switch according to figure 13 or 14.
