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 (B) 2 of the integration relay through the TAILLIGHT relay coil side, and to
TERMINAL (B) 3 through the HEAD relay coil side.
1. NORMAL LIGHTING OPERATION

With the light control SW turned to TAIL position, a signal is input into TERMINAL (B) 1 of the integration relay. Due to this
signal, the current flowing to TERMINAL (B) 2 of the relay flows to TERMINAL (B) 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 (B) 1 and (B) 4 of the integration relay.
Due to this signal, the current flowing to TERMINALS (B) 3 and (B) 2 of the relay flows to TERMINALS (B) 4 and (B) 1 to
TERMINALS 13 and 14 of the light control SW to TERMINAL 16 to GROUND, and causes TAILLIGHT and HEAD relay to
turn the lights on.
2. LIGHT AUTO TURN OFF OPERATION
When the driver's door is opened with the lights on and the ignition SW off, the relay is activated, and the current flow from
TERMINAL (B) 2 of the relay to TERMINAL (B) 1, and from TERMINAL (B) 3 to TERMINAL (B) 4 are cut, and all the lights
are turned off.
