The lighting circuits generally use Green wires. Newer 1200 utes differ.

Overview

The lighting circuits generally use Green wires.

• G - IG-hot from Fuse Box
• GY - Brake lights (stop lamps)
• GL - running lights (parking lights)
• GB - R.H. Turn Signal + running lights
• GR - L.H. Turn Signal + running lights

Turn Signals

The T/S path is as follows: From the IG side of the Fuse Box through the 10A "M" terminal (G wire) to the Four-Way Flasher Switch (Hazard Switch).

This Hazard switch is normally off and so routes power through G wire to T/S Flasher Unit. This means one side of the T/S Flasher is normally HOT -- but only if the key is ON. From the T/S Flasher unit the power goes to the T/S Switch on the column. In the center position of course the power stops here. But move the switch to right or left, and the power is fed to the Left or Right circuits to power all the exterior bulbs and the two dash bulbs. The T/S Flasher Unit causes the power to start/stop resulting in flashing.

• NILES Hazard flasher bolts to right side of column brace (G/L, G/W)

• NILES Turn Signal flasher bolts to left side of column brace
• W wire goes into steering column harness, up to the T/S switch
• G is the other wire

License plate lamp(s)

is simply connected to the rear-harness "tail" circuit (rear running lights -- GW wire). See above. But it is grounded locally, not through a harness wire.

Interior Dome Light

The room lamp has one side of the lamp (RL wire) always hot from the L wire of the fuse box. The switch has three positions:

• Off
• Auto (center)
• On

In the auto position, the light is grounded by the Door Switch (BR wire in a-pillar). Usually only the driver's side door has a switch. In the ON position, it is grounded through the ground wire in the headliner.

GR	Left-side T/S circuit	To Left-side (GR) T/S circuit To Instrument panel GR wire (left T/S lamp)

\*Labeled "Beam" for 1971. The other side of this light is grounded.

Brake lights

Brake lights (STOP lamps) -- thankfully -- are simply connected on the B110. At the rear light boxes, the GY wires connect to the main harness GY circuit. This is connected to the "Stop Lamp Switch" at the brake pedal. The other side of this switch (both are YG wires) is connected to Fuse Box GY wire ("H" terminal 15A always-hot). So brake lights work when key is off.

Instrument panel High Beam lamp

The IP brake lamp is not related to the rear brake lamps. Instead it signals if the hand brake is on ("Parking Brake Switch"), or if the master cylinder brake light switch ("Brake System Switch") senses a pressure differential problem.

Rear combination Lamp Box

</table> \*The rear wiring harness has a ground wire that bolts to the right-side rear bumper hold-down bolt (inside the car).

Reverse Lights are simply connected. The Red wire connects to the reverse switch on the side of the transmission. This switch in turn is fed from the G wire at the fuse box ("M" terminal of fuse box -- 10A fuse). It's always in affect, regardless of the Light Switch position. In other words, the Reverse light should work even if the headlights or running lights are off.
