GM All Lights Mod Installation
Step 1:
Remove the driver side kick panel to expose the
wiring just behind the OBDII connector. Next,
locate the BCM, which is found under driver side
of the dash to the upper left hand side. Remove
the brown BCM connector by pushing the tab
inwards and pulling down.
Step 2:
Identify the wires in each pin location on the
brown connector. Pin 10, shown here in red, is
located 3 rows up and 3 columns from the left.
Pin 18, shown here in green, is located 2 rows
up and 3 columns over from the right. Wire
color may vary between vehicles, therefore, pin
locations should be your primary reference.
Disclaimer:
Incorrect pin locations will result
in unexpected events such as
activating the horn. Relocate the
correct pin slots and move the T-taps to their
proper wires. T-taps can be reused if taken off
in one piece.
