10.6.1 Install DC Power Cable and Make Power and Ground Connections
1. Get the control head’s DC Power Cable from the its installation kit. This is part no. CA-012616-001
in Table 5-3 (CH-100) or Table 5-4 (CH-721).
2. Connect this cable to the large 3-pin connector at the rear of the head. Visually align the key and
gently push and turn the outer locking ring clockwise until it stops. A click will be sensed to confirm
proper mating.
3. At the back of the control head, locate a nearby section of vehicle chassis ground and strip this area of
any paint or dirt to expose a bare metal surface.
4. Cut the black wire of the control head’s DC Power Cable to the required length, plus a service loop of
at least six (6) inches, then strip it and crimp a ⅜-inch ring terminal to it. Two ring terminals of this
type are included with the cable.
5. Drill a hole, as necessary, and attach this ring terminal to chassis ground. Use stainless-steel self-
locking hardware (i.e., machine screws with washers and locking nuts) or other appropriate hardware
to ensure reliable terminal-to-metal contact. Tighten securely.
6. At the back of the control head, tie and stow the cable as necessary.
7. 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. as needed. Protect the wire from possible chafing as
necessary. This is the control head’s main DC power source.
8. Obtain one of the yellow waterproof (HFB-type) fuse holders included with the control head’s DC
Power Cable.
9. 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.
If necessary, a small amount of cable soap may be used to help slip the wire through the small end of
the fuse holder’s insulator.
10. 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) may be used if required.
11. Obtain the 5-amp AGC-type fuse included with the cable, and install it into the fuse holder.
The fuse for the control head’s red wire is rated at 5 amperes. The 3-amp fuse included with
the cable must not be used for fusing the control head’s main DC power. It fuses the head’s
white wire.
Do not share the control head’s fuse with any other device. Doing so can cause excess
current to flow through the fuse, causing it to blow unnecessarily.
