Wiring Notes:
There are two common types of dome light circuits, positive or negative switched. Positive systems supply voltage to the
interior lights to turn them on, negative switched systems apply ground to turn the lights on. To determine which system
you have, locate the wires at the dome light.
Positive switched system:
On a positive switched system, with all doors closed and lights out, both wires at the dome light will rest at ground. When
the dome light is activated, one of these wires will switch to +12 vdc. This is your switched wire.
For positive systems, connect the green wire (dome light trigger) to the switched wire. Then connect the brown wire
(dome light -) to a fused constant + 12 vdc source, and the brown/black wire (dome light +) to a ground.
Negative switched system:
On a negative switched system, with all doors closed and lights out, both wires at the dome light will rest at +12 vdc.
When the dome light is activated, one of these wires will switch to ground. This is your switched wire.
For negative systems, connect the green wire (dome light trigger) to the switched wire. Then connect the brown/black
wire (dome light +) to a fused constant + 12 vdc source, and the brown wire (dome light -) to a ground.
Some vehicles incorporate transistorized control of the dome light circuit, and may not support the additional current
draw of the unit's dome lights. On these vehicles it may be necessary to connect the green wire (dome light trigger) to a
door pin switch wire.
