DOME LIGHT CONNECTION
(1) NEGATIVE Door Circuit
Red wire
- Connect to 12V unswitched power.
Black wire - Connect to chassis ground.
This wire provides a ground. The lights will illuminate when the LSM104's 3-position dome
light switch is in the ON position. Failure to connect this wire to ground will prevent the
dome lights from illuminating with the switch in the ON position
White wire - Connect to negative door switch.
This wire will short to ground when a door is opened. The lights will illuminate if the
LSM104's 3-position dome light switch is in the DOOR position.
(2) POSITIVE Door Circuit
Red wire
- Connect to chassis ground.
Black wire - Connect to 12V unswitched power.
If there is no constant power wire under the factory dome light, a constant power lead will
have to be run to a source of unswitched 12V power.
White wire - Connect to positive door switch.
This wire will have 12V power when a door is opened.
IMPORTANT NOTE - NEGATIVE & POSITIVE DOOR CIRCUITS:
The 3-wire harness for the LSM104's built-in dome lights is color-coded for use in vehicles that
employ a
negative
door circuit. This includes most US and imported vehicles.
Most Ford Motor Company vehicles and some imported vehicles employ a
positive
door circuit.
First verify which type of circuit is used in the installation vehicle and then follow the instructions in the
