NOTE: When replacing the factory fitted CHMSL
with a canopy mounted CHMSL, the same type
must be used. Replace a bulb/incandescent type
only with a bulb/incandescent. Replace and LED
type only with an LED type.
NOTE: When cutting off the stop lamp circuit
wires from the 3-pin CHMSL connector, stagger
the cuts to allow for cleaner and less bulky splice
joins.
When fitting a canopy to vehicles equipped with
a combined CHMSL / Cargo Lamp, the lamp
housing may be impacted by the canopy. Check
the canopy to CHMSL clearance, and if required,
follow the below procedure.
A replacement CHMSL (without cargo lamp
function) needs to be installed. A patch harness
with a 2-pin connector is then spliced into the
vehicles CHMSL circuit wiring allowing a canopy
with an integrated CHMSL to take a stop lamp
circuit feed from the 2-pin connector. The original
3-pin connector is then taped back.
Follow the steps to install the replacement
CHMSL lamp housing:
1. Remove the combination CHMSL / Cargo Lamp
following the workshop manual instructions.
2. Locate the 3-pin CHMSL / Cargo Lamp
Connector. Cut off the stop lamp circuits (pin
1 yellow-grey or white-blue, pin 2 black-violet
or black-yellow or black-blue) leaving the violet
wire (pin 3) connected to the 3-pin CHMSL
connector.
3. Tape back the 3-pin connector with the violet
colored wire.
4. Splice the replacement 2-pin connector and
patch harness to the cut wires:
1. Yellow + Gray wire (or alternate color - see
above) to Yellow + Gray wire.
2. Black + Violet wire (or alternate color - see
above) to Black + Violet wire.
5. Insulate the spliced joins with heat shrink.
6. Route the canopy CHMSL wiring through a
suitable grommet into the passenger
compartment, route it behind the trim panels
and connect it to the replacement 2-pin
connector.
7. Install the replacement CHMSL to the vehicle
following the workshop manual instructions.
