With the ignition SW turned on, the current flows to TERMINAL 7 of the integration relay through GAUGE fuse.
Voltage is applied at all times to TERMINAL (C) 2 of the integration relay through the taillight relay coil side, and to
TERMINAL (C) 3 through the HEAD relay coil side (w/o daytime running light) or through the daytime running light relay
(Main) (w/ daytime running light).
1. NORMAL LIGHTING OPERATION
With the light control SW turned to TAIL position, a signal is input into TERMINAL (C) 1 of the integration relay. Due to this
signal, the current flowing to TERMINAL (C) 2 of the relay flows to TERMINAL (C) 1 to TERMINAL 14 of the light control SW
to TERMINAL 16 to GROUND, and taillight relay causes taillights to turn on.
With the light control SW turned to HEAD position, a signal is input into TERMINALS (C) 1 and (C) 4 of the integration relay.
Due to this signal, the current flowing to TERMINAL (C) 3 of the relay flows to TERMINAL (C) 4 to TERMINAL 13 of the light
control SW to TERMINAL 16 to GROUND in the headlight circuit, and causes taillight and HEAD relay to turn the lights on.
The taillight circuit is same as above.
2. LIGHT AUTO TURN OFF OPERATION
With light on and ignition SW turned off (Input signal goes to TERMINAL 7 of the relay), when the driver's door is opened
(Input signal goes to TERMINAL 6 of the relay), the relay operates and the current is cut off which flows from TERMINAL (C)
2 of the relay to TERMINAL (C) 1 In taillight circuit and from TERMINAL (C) 3 to TERMINAL (C) 4 in headlight circuit.
As a result, all lights are turned off automatically.

Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW.
When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL 8 of the light failure sensor, and also
flows through the rear lights warning light to TERMINAL 4 of the light failure sensor.
STOP LIGHT DISCONNECTION WARNING
When the ignition SW is turned on and the brake pedal is pressed (Stop light SW on), if the stop light circuit is open, the
current flowing from TERMINAL 7 of the light failure sensor to TERMINAL 2 and 1 changes, so the light failure sensor
detects the disconnection and the warning circuit of the light failure sensor is activated.
As a result, the current flows from TERMINAL 4 of the light failure sensor to TERMINAL 11 to GROUND and turns the rear
lights warning light on. By pressing the brake pedal, the current flowing to TERMINAL 8 of the light failure sensor keeps the
warning circuit on holding and the warning light on until the ignition SW is turned off.
