For 1990-2009 cars

The TAIL fuse applies voltage to the coil and the contacts in the headlamp relay at all times. With the turn signal/headlamp switch in the PARK or the HEAD position, the coil is provided a ground through the turn signal/headlamp switch to G200. When the ambient light sensor senses a low light condition, a path to ground is provided to the coil through the sensor to G200. When the coil energizes, the contacts in the tail relay close. The contacts apply voltage to the following components:

• | The left and right front turn signal and side marker lamps.

• | The left and right tail lamps.

• | The license plate lamp.

All of the lamps illuminate because the lamps are ground permanently.

With the ignition switch in the ON or the START position, voltage applies through the TURN fuse and the normally closed contacts of the hazard switch and the turn/hazard flasher to the turn switch. When the turn switch moves to the L position, voltage applies to the left turn indicator in the instrument cluster, the left front turn signal lamp, and the left tail lamp (turn lamp). The lamps are ground permanently. The lamps light immediately and start to flash 80-90 times a minute while the solid state timing unit in the turn/hazard flasher operates.

The lamps operate similarly when the turn switch moves to the R position.

Voltage applies at all times through the HAZ fuse to the normally open contacts of the hazard switch. With the Hazard Switch pressed, the contacts close. When the contacts close voltage applies through the turn/hazard flasher, back through the hazard switch, to the following components:

• | The turn indicators in the instrument cluster.

• | The front turn signal lamps.

• | The turn lamps in the tail lamps.

The lamps are ground permanently. The lamps light immediately and start to flash 80-90 times a minute while the solid state timing unit in the turn/hazard flasher operates.

Voltage applies at all times through the STOP fuse to the normally open contacts of the stoplamp switch. When the brake pedal depresses, the contact in the stoplamp switch close. The voltage applies to the tail/stoplamps in the left and right tail lamps and the center high-mounted stoplamp. The lamps are grounded to G400 and G401. The lamps light. The tail/stoplamps are dual filament. The stoplamps will operate even with the taillamps on.
