Options and Accessories Installation

: Emergency Pushbutton, Footswitch, Horn Relay, and Light Relay Installation 3-3

NOTE:

Remote Mount requires the VIP cable cable to be attached to J400.

3.2

Emergency Pushbutton, Footswitch, Horn Relay, and Light Relay

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 3-1

and

Table 3-2

).

Figure 3-2

shows how wires are plugged into the connector and how to use an

extraction tool to remove wires.

Figure 3-2. VIP Connector Detail

3.2.1

Emergency Pushbutton or Footswitch Installation

Mount the switch using the hardware that comes with the kit. Connect the emergency switch wires to
a ground pin and a VIP IN pin on the VIP connector.

3.2.2

Horn (External Alarm) Relay Installation

Mount the horn relay in a suitable location (normally under the dash). Connect the relay contacts
across the horn ring switch, typically found in the steering column. Connect the two control wires to a
SW B+ pin and a VIP OUT pin on the VIP connector.

3.2.3

Lights (External Alarm) Relay Installation

Mount the light relay in a suitable location (normally under the dash). Connect the relay contacts
across the headlamp ON/OFF switch. Connect the two control wires to a SW B+ pin and a VIP OUT
pin on the VIP connector.

CAUTION:

XTL 2500 radios equipped with the following features

are capable of transmitting automatically, even if the radio is turned
off:

• Automatic Vehicle Location
• Other Special Data Products

All XTL 2500 have accessory connector pins 14 and 15 connected
together to allow the radio to power down. Opening this connection
by REMOVING the accessory connector, or otherwise failing to
maintain a normally closed path, could, if left unchecked, drain the
vehicle battery, and possibly cause transmissions to occur.
