Standard Configurations Planning the Installation 2-15
2.1.3 Radio Operation Wiring for Dash and Remote Configurations
Determine from Table 2-1 or Table 2-2 the radio functionality you want to achieve, which is controlled
by the vehicle ignition switch state, the physical wiring of the radio ignition sense (ACC) wire, and by
the programmed CPS setting. For additional radio functionality as determined by the programming of
the ignition switch in CPS, refer to the HELP menu in your CPS that is Ignition as: Required, Blank,
Soft Power Off, TX Inhibit, PTT TX Inhibit, Ignition Only Power Up).
Choose a clean ignition point which is not shared in the immediate vicinity by other high current
accessories/devices to reduce the transients on the ignition line. Examples of
high-current accessories/devices are: Air Horn, relays, lightbars, and others. It is recommended to
wire to the vehicle ACC line, not the START or the solenoid side of the ignition circuit. Refer to
chapter 6 for best installation practices. The Ignition sense (ACC) cable uses either a 3-amp fuse
(6580283E01) or 4-amp fuse (6580283E02).
2.1.3.1 Dash Mount: Power, Ignition, and Emergency Cable Installation - Mid Power
The standard dash mount rear ignition sense cable HLN6863 contains a “thin red” ignition wire, a
jumper wire that shorts emergency to ground, and two gray wires attached to an external speaker
plug. The thin RED wire is the ignition sensed wire. Refer to Table 2-1 or Table 2- 2 for its correct
wiring configurations.
NOTE: This cable MUST be attached in order for the radio to operate in Dash mount, regardless of
how emergency is programmed in CPS or wired inside the vehicle. Either the emergency
jumper wire or an emergency accessory (footswitch or button) must be wired to the rear of the
transceiver in Dash mount. Otherwise, upon attachment of the radio power cable to the
vehicle battery, the radio incorrectly determines that emergency operation has been
activated, such as when an emergency footswitch is de-pressed and the emergency pin is
ungrounded.
