8.2.2 Main Power (Red Wire and Main Fuse Holder) Connection
1. Continue installation of the radio’s DC Power Cable by routing its 20-foot 10-AWG red wire to the
location of the vehicle’s battery (or its main DC bus bar or stud).
Remove interior panels, door kick panels, etc., and route the wire through existing channels in the
vehicle body as necessary. Protect the wire from possible chafing where necessary. Tie and stow the
wire as necessary.
2. Obtain the orange-wired inline blade fuse holder included with the DC Power Cable.
3. Observe and follow the previously presented Battery Ground WARNING!
4. Cut the red wire to the required length for connection to the battery’s positive (+) battery terminal (or
the main DC bus bar or stud).
5. Strip the wires coming from the fuse holder approximately ⅜-inch.
6. Cut the wire of the DC power cable and strip ends of the wires approximately ⅜-inch.
7. Slide heat shrink over end of each wire.
8. Place the yellow splice connectors on the DC power wire and securely crimp.
9. Insert wires of fuse holders into the splice connectors and securely crimp.
10. Slide heat shrink down over splice connectors and use heat gun to seal.
11. Label this fuse holder and red wire appropriately (e.g., “XL Mobile Radio Main Power: 20-AMP
FUSE”).
Do not install a fuse into the fuse holder at this time.
12. Crimp an appropriate electrical terminal to the short red wire. A corrosion-resistant ⅜-inch ring terminal
is included with the cable for this purpose, but another size corrosion-resistant terminal type (not
supplied) may be used if required.
13. Connect the ring terminal directly to the battery’s positive post (or if present, to a stud on the battery’s
main/non-switched power distribution terminal block).
A front-mount XL Mobile radio installation can be connected to an additional Control
Head to form a multiple control head radio installation. In this case, refer to Section 9.2.2
for Control Head installation procedures.
8.2.3 Ignition Sense (White Wire) Connection
A review of the Ignition Sense Location and Considerations information presented in Section 6.3.3, on page
30 may be beneficial at this time. As required per the chosen power-up configuration, connect the white
wire by following one of the three procedures presented in the respective sub-section that follows.
