2. The electrical power switch (item #7) provides power for the crane. Install the switch onto the power unit cover.
3. Install the vehicle level indicator (item #8) parallel to the door reinforcements.
4. After mounting your crane, wire the crane to the vehicle’s 12VDC electrical system using the following steps.
Use the parts list above to identify parts. Your crane installation kit, 51721572, includes a 10.7 m (35’) long
cable, IMT # 89044276 (item #13 in the parts list). Approximately 7.6 m (25’) of this cable is required to connect
the crane power switch to the vehicle battery, and the rest of the cable is used for ground connections between
the crane, vehicle battery, auxiliary battery, and chassis ground. Cut the cable to length after determining the
lengths required.
5. Ground the crane by connecting the crane ground cable to bare metal inside the crane box.
6. Connect the crane power cable from the male power cable connector to the power switch. Connect cable (item
#13 - 89044276), cut to length, from the crane power switch (item #7) to the fuse. Use 3/8” (0.95 cm) ring ter-
minals (item #9 - 77040209) for each connection. Heat shrink the connections (item #14 - 89392333).
