Installation into the Vehicle

CAUTION
1. Disconnect the negative terminal from the vehicle's battery. Make sure that the battery cable
is secured such that it will not power the vehicle's electrical system.
2. Place the accessory connector assembly in the approximate location for the permanent
installation of the radio. Allocate a sufficient service loop for ease of removing and servicing
the radio.
3. Route the ignition wire to either an ignition switch circuit or a power source that is always hot
(see Section 2.4 on page
withstanding a load of 4 amps (see the wiring diagrams in the vehicle manufacturer's service
manual). Always use the supplied fuse holder to prevent damage to the radio.
4. Secure wires with tie straps or electrical tape to prevent damage to or entanglement of the
wire. If wires are passed through drilled holes through firewalls or through any other metal
panels within the vehicle, the holes must be fitted with a rubber grommet (not supplied) to
prevent shaving of the wire's protective jacket, which could cause electrical shorting.
NOTE: If the speaker pigtail is connected to the speaker assembly (optional), Be sure not to route the
speaker pigtail or wires through any areas that could cause potential damage to them. The
audio system is a floating ground; therefore, any speaker lines that come into contact with the
ground can cause damage to the radio. Check all wires for electrical shorts; properly repair
any electrical shorting issues immediately.
5. If there are no issues, reconnect the battery. Follow the vehicle manufacturer's instructions
for the proper procedure.

Installation onto the Radio

The accessory connector assembly is fastened to the back of the radio by jackscrews. The radio
should be fully mounted and secured in its trunnion prior to connecting the accessory connector
assembly to the radio. Be sure when connecting the accessory connector assembly to the radio that
there are no foreign materials in the mating surfaces. Do not force the connector on. It should slide
on with very little resistance. Be sure that both jackscrews are engaged in their threaded holes
before tightening them. Finger tighten the jackscrews securely to prevent loosening.
