the firewall, drill a 5/8 inch hole and insert the rubber grommet provided. If the

battery is located on the passenger side of the vehicle, the battery leads should

cross the vehicle in front of the engine. All attempts should be made to maintain

as much distance as possible between the radio power lead and any vehicle

electronic modules and wiring. Be sure to keep these leads mounted so they

cannot snag on any moving part of the engine. Connect the red lead to the

positive (+) battery terminal and the black lead to the negative (-) battery

terminal. Always locate the fuse as close to the battery as possible. Coil up the

surplus cable and secure it out of the way with the retaining strap provided. Be

sure to leave some slack in the cables going to the radio so that it may be pulled

out for servicing with the power applied.

IGNITION SWITCH CONTROL

With ignition switch control, the transmitter and receiver operate only with

ignition switch in the Accessory or On position. Connect the yellow fused lead

to the ignition switch terminal. Then remove the jumper between A+ and the

ignition lead on the system power cable plug (see Figure 2).

If the ignition switch control is not used, cut and tape the end of the yellow lead

to prevent shorts and do not cut the jumper between A+ and the ignition lead on

the system power cable.

With some accessory points, the voltage only drops when the ignition switch

is in the START position. A connection point should be used where the

voltage is completely off when the ignition switch is in the START position.

If electrical noise is excessive at the accessory block, install alternator noise

filter option MLPDlA.

Certain problems may be encountered when accessory equipment is

connected to the ignition or accessory lines of the vehicle, where these lines

may have large filter capacitors or a leakage path is present.

If the radio does not turn off within a reasonable amount of time after the

ignition is turned off, first try a different accessory or ignition sense pick up

point in the vehicle. Many vehicles have more than one circuit that is

switched by the ignition switch, and one may be available that does not have

large filter capacitors or a leakage path present.

If a different pickup point cannot be found, try adding a 470-ohm, 1-watt

resistor from the ignition sense pickup point to ground. This will discharge

the capacitor(s) or reduce the leakage voltage to a low value. Current drain

through this resistor will be minimal (less than 0.03A) when the ignition is

switched on.
