ELECTRICAL CONNECTIONS
TRUCK BED LIGHTS
Your truck bed wiring terminates at the end with a pre-wired 7-way socket. A
companion pre-wired 7-way plug is included in the ship loose package and must
be wired into the truck wiring system. Once wired in simply plug both ends
together and check your lights for correct operation.
Some Eagle Bed models have a 16-2 wire, terminated near the front driver side,
which must be wired into the truck wiring system. Once wired in check your
lights for correct operation.
TRUCK BED DC POWER UNITS
In the front of the truck bed there is a pre-wired 2-way socket. A companion
pre-wired 2-way plug is included in the ship loose package and must be wired
into the truck wiring system. The red wire must be connected to the battery
positive post. A 200-amp breaker and the black wire must be connected to the
battery negative post. It is recommended that the 200-amp breaker be installed
in the battery box.
TRUCK BED DOOR CONTROLS
Located in the front of the truck bed are two pre-wired 4-way sockets. Two
companion 4-way plugs, pre-wired with 16-3 wire, are included in the ship loose
package and must be wired into the cab mounted switches for the side and rear
doors. Once the DC Power Units and Cab Switches are wired, test the door
controls for correct operation. Note: a third pre-wired switch, located at the
driver side rear of the bed, must also be tested at this time. No additional wiring
is required for this third switch.
