The yellow or red speed sense wire inserts into the firewall's hydraulic unit on the vehicle's driver's side.

The diagram continues, showing the orange or yellow parking lights hooked into the light switch. The green or black reverse lights wire threads through the harness in the driver's side kick panel toward the back of the vehicle. The green or red brake lights wire hooks into the switch located above the vehicle's brake panel, while the black or blue horn wire inserts into the last space in the ignition switch harness. The factory anti-theft system signals through the ignition cylinder to the immobilizer when the remote starter is deployed.

Remote start systems provide the convenience of starting vehicles without inserting keys into the ignitions. They are available from many companies; Ford, for example, produces a bi-directional remote start system that is compatible with vehicles with automatic transmissions. The start button on the key fob starts the engine when pressed. To verify the vehicle's ignition, the green button on the fob flashes, and the device beeps.

In addition to starting the vehicle at a distance, a remote start system possesses a panic button for use in emergencies. It is also equipped with the progressive car find program that locates lost vehicles.
