4.2 Remote-Mount Accessory Installation
Perform the following installation procedure:
1. Select an appropriate place to mount the option or accessory hardware.
2. Route the accessory-to-control head cables under floor coverings or behind panels so that
the vehicle occupants do not snag or break the wires.
3. Attach wires from the accessory to the appropriate wire on the VIP cable (see Table 4-1 and
Table 4-2).
The radio is sold with correct accessory cables and jumpers in order to have
emergency de-activated by default, regardless of the setting in CPS. However, if
cables are not used, or if jumpers are removed without replacing with an emergency
accessory button/switch at one of the accessory ports, the radio will power-up upon
the application of A+. The display may not show an indication that the radio is on, and
this can result in an incorrect operation of the radio as well as excessive current drain
of the vehicle’s battery when the engine is off.
