In the fall of 1984 a sales merchandising activity featured the Centre High-mounted Stop Lamp as standard equipment on all 1985 FWD DeVilles and Fleetwoods. Production of this feature was to have begun Septemer 4, 1984 but unfortunately, sufficient parts were not available until November 19, 1984.

#### PARTS INFORMATION

Parts required to complete this Special Policy should be obtained from the Parts Distribution Centres. The following parts are to be used:

Description Usage Part Number ----------- ----- ----------- Kit, Centre High Mounted 1985 FWD DeVille 16506254 Stop Lamp* and Fleetwood

* The kit includes three brackets and two pedestals to accommodate each rear deck shelf panel design.

#### SERVICE PROCEDURE

1. Using masking tape, cover an approximate 8 in. x 8 in. area on rear deck shelf trim near centreline of vehicle. Determine exact centreline of package shelf and mark this centreline on masking tape.

For cars equipped with rear window glass inserts (Fleetwood and cars equipped with vinyl roofs) remove pedestal attached to lamp assembly and install higher pedestal P/N 16504071 on lamp assembly.

Paint lamp assembly and pedestal to match interior colour of car.

2. Centre base of pedestal on centreline marked on taped area on rear deck shelf trim in Step 1. Position lamp assembly with rubber shroud contacting rear window glass (shroud will prevent light reflection into passenger compartment). Trace outline of lamp assembly pedestal on taped area in this position.

To determine which mounting bracket is required for the vehicle, open the trunk and look at the underside of the rear deck shelf panel:

If the rear deck shelf panel is flat in the area where the lamp assembly is to be located, use support No. 20557018 (shallow support with 1 in. hole in centre).

If the rear deck shelf panel has a bulge in the area where the lamp assembly is to be located, use support No. 20565299 (deeper support with no hole in centre, 1/2 in. hole must be drilled in centre of bracket).

If the rear deck shelf panel has a bulge in the area where the lamp assembly is to be located and has a plate with rows of holes in it attached to bulged area, use support No. 20565298 (deeper support with down-turned tabe at one edge, 1/2 in. hole must be drilled in centre of bracket).

3. Once correct mounting bracket has been determined, position the mounting bracket inside the traced outline of pedestal in Step 2. Centre the mounting bracket side-to-side and front-to-back and trace outline of mounting bracket on tape. Using a sharp knife, cut and remove the rear deck shelf trim (including accoustic insulation) enclosed within the outline of the mounting bracket. Do not cut out the area enclosed by the base of the pedestal.

4. From inside the passenger compartment, place mounting bracket in area cut out in step 3 and mark the two bracket mounting holes and the centre hole in bracket on the rear deck shelf panel. From inside the passenger compartment, centre punch and drill the two 1/4 in. mounting holes, if required, and a 1/2 in. centre hole.

5. Secure mounting bracket to rear deck shelf using screws, washers and nuts provided in installation kit. Do not attach lamp assembly to mounting bracket at this time.

6. Carefully remove rear seat, rear seat back, and insulation pad behind rear seat. Drill 1/2 in. hole in sheet metal behind rear seat back. Hole is to be located on centreline of lamp assembly 2 in. below edge of rear deck shelf trim.

7. Install the connectorless end of the wire harness through the hole in rear seat back sheet metal and through the centre hole in the rear deck shelf. Install rubber grommet for hole in rear seat back sheet metal and inatall both wire ends in connector provided in kit. (Orientation of wires in connector is not critical.)

8. Route wire harness down right hand side of car to junction block located behind glove box. Harness is to be installed underneath carpeting. To accomplish this, carefully remove the seat belt retractor, lower 'B' pillar trim, right side sill plates and right hand kick panel. The harness should be placed underneath the carpet far enough so it does not interfere with trim when reassembling. Reinstall rear insulation pad, rear seat back, and rear seat.

9. Remove glove box for access to the junction block. Remove dark blue with white stripe jumper wire located in cavities J and K of the black 11 pin connector on the right side of the junction block. Install jumper harness from kit in cavities J and K of this same junction block connector and connect blue wire of centre high mount stop lamp harness to the jumber harness. The black wire of the centre high mount stop lamp harness should be plugged into the open 2 pin connector space located on the lower left side of the junction block connector. Reinstall glove box.

10. Test for proper operation of Centre high mounted stop light. The light should light when the brake pedal is depressed. The light should not light when turn signals are activated. The Dealer installed centre high mount stop lamp will flash with the hazard flashers. The factory installed stop lamp will not flash with the hazard flashers.

11. Remove remaining masking tape from rear deck shelf trim. Complete final installation of lamp assembly to mounting bracket using two sheet metal attaching screws provided in kit. To prevent light reflection into passenger compartment adjust the pedestal rearward until the rubber shroud of the lamp assembly is in contact with the rear window glass.
