Step 13
Fasten the 150 AMP circuit breaker provided within 2 ft. of the truck battery. Route
battery cable from the pump enclosure toward the 150 AMP breaker. AVOID SHARP
CORNERS AND HIGH HEAT AREAS! Use cable clips provided to secure the cable to
the truck frame every 2 feet. Cut the cable to the desired length and strip .88" of
insulation from the end. Slide the pre-cut heat shrink over the end of the cable.
Secure the cable lug in a vise and apply heat to the connector and insert the cable as
the solder melts. Allow connector to cool and install the heat shrink. Attach this end to
one terminal on the 150 amp circuit breaker. Install heavy ground cable from negative
battery terminal to the frame. Wire the breaker to the truck battery using the 2ft. cable
provided. Bolt the grounding cable to the truck frame. See figure 12.
Step 14
Many late model trucks have battery connections as shown in figure 12. The ground
cable from the battery may be run directly to the engine block with only a light braided
ground strap connecting the block to the chassis. Where this is the case, the factory
installed cable usually does not provide an adequate ground circuit for operating
battery powered liftgates. We recommend that the cables labeled with an "X" be not
less than #2 gauge cable as supplied in the installation kit. Also because of the high
current draw (Approximately 200A) we recommend that the alternator be a heavy
duty type and the battery must have a 150 AMP minimum reserve capacity.
