The Purkeys Direct™ system improves the charging of liftgate
batteries by utilizing a DC/DC Converter to boost the voltage for
optimal charging. The boost in voltage overcomes the normal
voltage drop caused by the extended distance between the
liftgate batteries and the vehicle charging system. Also, in cold
temperatures batteries require increased charging voltages to
maintain a high state of charge. The DC/DC Converter in the
Direct system compensates for temperature as well as for voltage
drop and provides the best voltage to the remotely located liftgate
batteries. The result is well-charged liftgate batteries that will last
longer and have ample power for liftgate operation.
The Direct system is automatic and has easy to interpret LED
indicators to assure drivers and technicians of proper system
function. The Direct Controller increases the time that the DC/
DC Converter can charge the liftgate batteries by monitoring the
source power and “extending” the liftgate battery charge time to
take full advantage of the available power, without compromising
the source batteries’ ability to crank the engine. Simply put,
the Direct system provides opportunity charging for the liftgate
batteries that is essential in low mileage, high frequency liftgate
operation applications. The LED indicators clearly show the
status of the source as well as the status of the liftgate batteries.
A quick glance at the Direct Controller assures the driver that
the liftgate batteries are ready to go, or alerts the driver that the
batteries need maintenance.

Note: The dual/single pole nosebox must be mounted with the
wires facing down to help prevent water intrusion.
Direct Controller Mounting Complete.
MOUNTING THE DIRECT CONTROLLER
Step 1: Mount the Direct
Controller at the front of the
trailer via the mounting holes
on the mounting plate.
Step 2: Mount the dual/single
pole nosebox to the front of
the trailer close to the Direct
Controller. The connections
to the Direct Controller have
already been made.
Note: Do not block the LED
status decal on the side of
the Direct when mounting the
Direct Controller.

DIRECT-02 INSTALLATION GUIDE
Step 1: Route the Direct
jacketed 4-conductor main
harness for the DC/DC
converter behind the front
plate, then behind the header
plate through the air/electrical
tube to the center channel.
Step 2: Route the Direct
jacketed 4-conductor main
harness in the center channel
toward the back of the trailer.
Secure with wire ties or cable
clamps as you go.
Step 3: Once you are near the
liftgate battery box, begin
routing the Direct jacketed
4-conductor main harness
into the liftgate battery box
through a dome nut or rubber
grommet.
MAIN HARNESS INSTALLATION
Note: Place the cable clamps along the 4-conductor jacketed main
harness every 6 inches to ensure proper support for the cable.
Avoid sharp edges and possible chaffing points.
Note: Ensure that the jacketed 4-conductor main harness enters
the liftgate battery box through a dome nut or rubber grommet
to prevent chaffing the harness, which could result in possible
electrical short in the system.

6
Step 4: Position the Direct
jacketed 4-conductor main
harness so that it will reach
the 2-stud strip and all
the slack has been taken
up. Mark the jacketed
4-conductor main harness
so that it can be taken back
out of the battery box to be
terminated.
Note: If your battery box includes a slid-out tray, include enough
slack to allow the tray to fully extend without tugging the wire
connections.
Step 5: Pull the jacketed
4-conductor main harness out
of the box (making it easier
to work on), and cut off the
excess at the mark.
Step 6: Cut about 8 inches off
the jacketed portion of the 4
wires.

Step 7: Apply the supplied ¾
inch black heat shrink where
the jacket was stripped off.
Step 8: Strip 3/8 inch of
insulation off all 4 wires.
Step 9: Slide the supplied red
¼ inch heat shrink over the
orange, yellow, and black
wires. Slide the supplied black
¼ inch heat shrink over the
white wire.
Step 10: Crimp 3/8 ring
terminals onto the white and
black 8-gauge wires. Crimp
#10 ring terminals onto
the 14-gauge orange and
16-gauge yellow wires.

8
Step 11: Position the heat
shrink over the crimps and
apply heat to the 4 terminals.
Step 12: Re-route the jacketed 4-conductor main harness back into
the battery box (see diagram on page 3 for stud location).
• Connect the 8-gauge black wire to the red positive input stud.
• Connect the 8-gauge white wire to the black ground stud.
• Connect the 14-gauge orange wire to the liftgate (+) stud.
• Connect the 16-gauge yellow wire to the ignition stud.
Main Harness Installation Complete.
