IMPORTANT: Make sure the connectors wires are passing over the deflector wings and away
from any sharp edge.

•

From outside of the vehicle, connect the Plasma 5 & 6 connectors at the back of the plasma
cluster modules (order is not important).

•

Install the missing # 502799 screws and # 500855 washers and secure the modules to the
support (do not overtight).

•

Secure the support to the duct using 8 supplied # 500957 screws.

•

Pull out the connectors from the upper grommet in the parcel rack floor (next to the HVAC unit).

NOTE
In some vehicles not equipped with parcel rack doors,
the hole & grommet may not be present.
In this case, the hole must be drilled using a suitable
hole saw and the provided # 504534 grommet.

•

Pass the connectors in the lower floor grommet (HVAC harness grommet).

•

Remove the over head light/register console to access the connector from under the parcel rack
HVAC unit.

7. Install 2 plasma cluster modules # 0610449 in the area below the left parcel rack HVAC unit.
•

With a sharpie, mark the location of the # 314937 supports (2X) on the inner parcel rack rail. Both
supports must contact the extrusion edges, one on both sides (the support back shape must fit
the ribbed extrusion profile horizontally as shown).

•

Drill the 4 mounting points for a # 8 screw (1/8 or 9/64th inch drill bit).

•

Install 2 of the supplied # 0610449 plasma cluster modules on the supports using supplied #
502799 screws and # 500855 washers.

•

Connect the Plasma 3 and the Plasma 4 connectors (previously routed to the underside of the
parcel rack) to the two modules. Leave +/- 6 inches of wire behind the module to ease future
removal / installation during maintenance.

•

Secure the supports (and modules) to the extrusion using the supplied # 500443 screws.

Connect the C581 connector of the # 0610504 harness (previously routed under the HVAC unit
with Plasma 3 & 4 connectors) to the C581 connector of the long # 0610505 extension harness.

•

Using a fish tape or a long flexible rod, pass the # 0610505 harness inside the parcel rack frame
up to the driver’s pillar area.

•

Follow the pillar down (use cable ties) and using a flex rod, fish the harness inside the front
electrical junction box.

•

Secure the harness inside the front junction box (in the upper area from rear to the front)
