This will be more a how to than a question or problem so if I'm in the wrong spot, can one of the mods please move this

Just added new lights! Full write-up to follow...

Was your mod to change out the red reflector from the oval shaped area just under the arm rest? I was wondering if the wiring might still be in the door, and if just buying the assembly may do it. I look forward to your write-up.

Changing the lamp assembly was just part of it. There is no wiring in place for 2001+ so I had to add it all. Lots of work but I used actual Delphi terminals and added the applicable wires to each of the harness segments. I just need to organize all my photos and write up the text. Hopefully this weekend depending on how busy I am at work

im next in line for this particular mod

Just curious... where did you get the light assembly for each door? I've run my wiring, but need to get the fixtures.

Looks good! Did you run your wires inside the door to body boot or did you cheat like me and run it thru the rubber around the door glider?

looks nice..

I purchased the lamp assemblies from GM. Haro was kind enough to provide the part number since they were easily accessible during his recent car renovations

I added wires to each segment of the applicable wiring harness sections throughout the car. I purchased all the required terminals so I could utilize the existing vehicle connectors. I'm going to post pics here as soon as my write-up is all done.

Adding Door Panel Courtesy Lighting, 2001+ Bonneville.

This process was completed on a 2004 GXP but should be similar, if not identical, for all other 2001+ Bonnevilles. This of course doesn’t apply to the 2000 model year as these were standard equipment in those vehicles.

I have attempted to provide clear and accurate information but there is a possibility that errors or omissions exist. If I find or am made aware of any, corrections will be posted. I may also provide further information if any becomes available.


Here'* what’* different:
First, in the 2001+ cars there are no wiring provisions in place. This means it isn’t as simple as just snapping in the new lamp assemblies. Second, the lamp assemblies are different. The 2000 model year lamp is a smoked colour. Additionally, they come with electrical conductors and #74 incandescent bulbs. 2001+ are red in colour. The cutouts are in place for the bulbs but there are no electrical conductors. Having said this, it would be possible to purchase the smoked colour assemblies and transfer the conductors and bulbs to the red assemblies if this colour is preferred. Physically the two assemblies are the same size and shape.

There are several different parts required to complete this depending on how much of a “factory appearance” you want to achieve. I decided to compromise such that most people wouldn’t know it wasn’t factory, but if a person really started digging through manuals would be able to figure it out. For the purpose of this write-up, I’ll go through the steps I followed. These steps can be modified to some extent.

About the procedure:
The project can be broken into several smaller segments. These are:

1. Add the lamp module to each door panel.
2. Add wiring to each door panel wiring harness.
3. Add wiring from each door panel harness to the vehicle body harness.
4. Add wiring to the body harness for each door.
5. Make final connections to the courtesy lamp circuit under the rear seat.


About the lamp assemblies:
The assemblies I used were for the 2000 model year Bonneville. The part number is 16634063. Thanks to Harofreak00 for providing me with this number! Four are required and they are the same for each door. As stated, these come with the lamps and conductor rails. A separate connector plugs into the lamp assembly.




About the wiring:
GM has specified that 0.35mm2 (SAE 22 gauge) conductor be used. The colours are ‘Gray’ and ‘Dark Blue w/ White Stripe’. Gray was easy to acquire, but the dark blue with a white stripe was only available if I purchased a 100,000 foot roll. Needless to say, this wasn’t a reasonable option and a solid ‘Blue’ conductor was used instead.

Connections into the courtesy lamp circuit are made under the rear seat by adding conductors to pre-existing splice packs. These are taped up as part of the main wiring harness that runs from the left to right side of the car and is just behind the rear power distribution centre. More details on this later.


Required connectors NOT already in the vehicle:
Lamp Assembly Connector
GM Part Number 12059249
2-Way Metri-Pack 150 Series Unsealed Connector (Natural Colour) - Female
Not available from GM Parts.
Best Source is an auto wrecker. Same connector as used for courtesy lights on mid-late 90’* Bonnevilles



Building the wiring harness segments:
The following wiring segments are based on a 2004 GXP. There is no reason to believe they won't be the same as other 2001+ model year vehicles, however it is possible that GM production techniques changed causing a variance.

Each segment of wiring will require both a gray (‘GRY’) and blue (‘BLU’) conductor. Two wires and four terminals are required for each segment. A total of 12 segments (24 wires) must be built and added. The wire length specified is in inches unless otherwise specified (some measurements include feet and inches). These lengths are for the wire itself BEFORE terminals are attached. The addition of terminals will increase the length of the specified measurements. See **Legend at the bottom of this section for further details.

Preparing for installation:
To access all required areas, the following steps must be completed:

1. Disable SIR zones 2 & 6.

Extreme care must be used when working on or around the Supplemental Inflatable Restraint (SIR) system. Failure to do so can result in serious injury, death and/or unnecessary repairs. Do not attempt these procedures unless you are familiar with these systems and procedures.

DISABLING:
1. Position the steering wheel so that the front wheels are pointing straight forward.
2. Turn the key to the OFF position and remove it from the ignition.
3. Remove the rear seat cusion (procedure below).
4. Remove the rear fuse block cover.
5. Remove the SIR fuse.
6. Remove the LEFT & RIGHT 'B' post garnish moldings (procedure below).
7. Remove the connector on each of the SIR sensors. These are mounted at the base of each 'B' post on the interior of the vehicle. They are labelled as part of the SIR system and will have yellow connectors. You will need to remove the CPA (connector position assurance) lock before the connector can be released and unplugged. ** DO NOT WORK ON THESE CONNECTORS BEFORE REMOVING THE SIR SYSTEM FUSE **

RE-ENABLING:
1. Follow above steps in reverse. Be sure not to reinstall the SIR system fuse until the 'B' post garnish moldings have been replaced.
2. Once all steps are complete, use CAUTION and reach into the vehicle, insert the key and turn to the ON position. The AIRBAG light will illuminate and then turn off.

2. Remove the kick panel under the dash by the driver and front passenger feet.
See the 'Procedure w/ Pictures' section below for instructions.

3. Remove the carpet retainers just inside each of the four doors.


REMOVAL:
1. Open the door.
2. Unsnap the carpet retainer.
3. Remove the carpet retainer from the floor.

INSTALLATION:
1. Install the carpet retainer to the floor.
2. Snap the carpet retainer into place.
3. Close the door.

4. Remove the LEFT and RIGHT ‘B’ pillar trim panels.


REMOVAL:
1. Remove the front and rear carpet retainers.
2. Disable the SIR system (Zones 2 & 6). There are airbag sensors behind these panels.
3. Pull out on the centre trim panel to disengage the clips. Use caution as this is a two part molding. There is a plastic weld half way down (where the color changes) that can be broken if care isn't exercised.

INSTALLATION:
1. Position the garnish molding in place. Position the weatherstip over the edge of the molding. Press the molding in place to engage the retaining clips.
2. Install the front and rear carpet retainers.
3. Enable the SIR system (Zones 2 & 6).

5. Remove the rear seat cushion.
REMOVAL:
1. Pull straight up on the lower forward edge of the seat cushion.
2. Remove seat cushion from the car.

INSTALLATION:
1. Place seat cushion in car. Ensure all seat belts are positioned for access.
2. Press downwards on forward portion of seat cushion to snap in place.

6. Remove all four door trim panels.
Harofreak00 has put together a great write-up for removing/installing the door panels.

Project Complete:



A note on parts availability:
A limited number of harness sets can be made available for anyone wanting to add these lights. Please PM 'ddalder' for details.

amazing as always

Very nicely done. I sooooo jury rigged mine - but i live in a condo - no garage and not enough time. You gave me, and others, very good info.

Thank you very much.
