Do not ground the black wire by attaching it via the same hardware that secures
the cable’s mounting bracket.
Before drilling holes and/or installing mounting screws, verify these operations will not
damage or interfere with any existing vehicle component (the fuel tank, a fuel line, the
transmission housing, existing vehicle wiring, etc.). Always check to see how far the
mounting screws will extend below the mounting surface prior to installation. Always
deburr drilled holes before installing screws.
5. Tie and stow the cable near the HHC-731 Interface Cable’s bracket.
6. For the positive 12-volt DC main power source connection, route the cable’s red wire to the location
of an unswitched
12-volt DC power source, typically near the vehicle’s battery. Remove interior
panels, door kick panels, etc. Protect the wire from possible chafing as necessary. This is the hand-
held controller’s main DC power source.
7. Obtain one of the waterproof (HFB-type) fuse holders included with the DC Power Cable.
8. Cut excess length from the red wire and splice the fuse holder into it, near the location of the
unswitched 12-volt DC power source connection point.
9. Using an appropriate electrical terminal, connect the red wire to the unswitched DC power source. A
⅜-inch ring terminal is included with the cable for this purpose, but another terminal type (not
supplied) should be used as required.
10. Obtain the 5-amp AGC-type fuse included with the cable, and install it into the fuse holder.
Do not share the HHC-731 hand-held controller’s fuse with any other device. Doing so
can cause excess current to flow through the fuse, causing it to blow unnecessarily.
The fuse for the HHC-731 hand-held controller’s red wire is rated at 5 amperes. The
3-amp fuse included with the cable must not be used for fusing the controller’s main
DC power. The 3-amp is used to fuse the controller’s white wire.
8.4.3.2 Connect DC Power Cable’s White Wire
Connect the DC Power Cable’s white wire by following one of the following three procedures, per the
customer’s required on/off power control method:
8.4.3.2.1 Hand-Held Controller and Radio Turn on with Vehicle’s Ignition Switch/Key
With this wiring configuration, the HHC-731 hand-held controller and the radio turn on and off with the
vehicle’s ignition switch/key (power on also requires pressing of the HHC-731’s front panel power on/off
button). The white wire of the HHC-731’s DC Power Cable is sometimes referred to as the “white
ignition switch wire” or the “ignition sense input wire.” In this configuration, the white wire of the
HHC-731’s DC Power Cable connects to a switched power source, typically identified as “Accessory”
power, that switches on and off with the vehicle’s ignition switch/key.
