INSTALLATION OF RADIO SYSTEM
The control modules and control unit have been designed with sufficient attention to radio wave disturbances from the outside. However, observe the following precautions when installing the radio set to the vehicle to prevent adverse effects on the control modules and control unit.
Scheme 30
- Install the radio set and its antenna as far away as possible from the control modules and control unit.
- The antenna feeder and power cable generate radio waves, therefore, keep them 100 mm {3.94 in} or more from the control modules, control unit, and wiring harness. If the antenna feeder and power cable cross over the wiring harness, place them perpendicular to the wiring harness.
- Do not install a high output radio set.
- Do not use the control modules and control unit power source for the radio set. In addition, do not use the cigar lighter and accessory socket power source.
- Do not attach the antenna feeder or wiring harness of the radio set to the wiring harness, fuel pipe, or brake tube of the vehicle.
- Do not install any radio set-related devices in the area where the air bag module deploys to prevent a secondary accident if the air bag were to deploy.
- After installing the radio set, perform a test transmission with the engine idling to verify that it does not affect engine control.
Scheme 31
- Before disconnecting connectors or removing electrical parts, disconnect the negative battery cable.
Scheme 32
Scheme 33
- To remove the wiring harness from the clip in the engine room, pry up the hook of the clip using a flathead screwdriver. CAUTION: Do not remove the harness protective tape. Otherwise, the wires could rub against the body, which could result in water penetration and electrical shorting.

Scheme 35
- When disconnecting connector, grasp the connectors, not the wires.
- Connectors can be disconnected by pressing or pulling the lock lever as shown.
Scheme 36
- When locking connectors, listen for a click indicating they are securely locked.
