DOME LIGHT CONNECTION

IMPORTANT NOTE - NEGATIVE & POSITIVE DOOR CIRCUITS:
The 4-wire harness for the LSMD104's built-in dome lights is color-coded for use in vehicles that
employ a negative door circuit. This includes GM (excepting 2003 and later full-sized SUV's),
Chrysler and most imported vehicles.
Most Ford Motor Company vehicles and 2003 and later GM full-sized SUV's employ a positive door
circuit.
First verify which type of circuit is used in the installation vehicle and then follow the instructions in the
appropriate section below.
