The light kit comes with everything required to install, except it is also recommended that you apply a little silicone/sealant to ensure a lasting seal around the holes & wires.
The installation takes approximately 2 to 3 hours and can be broken down into 5 main steps:
1. Drop front part of headliner
2. Measure/Mark holes for lights
3. Mount Lights
4. Wire Lights
5. Re-assembly
Drop Headliner
Remove sun visor assemblies and sun visor clamp (Torx 15 & 20 required)
Disengage passenger side grab handle. Insert small flat screwdriver to pull out covers/lock mechanism then pull out on handle until you feel it disengage. There is no need to remove handle from headliner.
Disengage DS and PS pillar covers. Pull out at top and away from pillar. Lower panel(s) down so you can drop headliner about 4-6”.
Remove overhead console. Remove front screw. Slide console forward a little and pull down in rear as is a clamp on each side that locks it into the overhead. Disconnect On-Star speaker plug (if equipped) and map light plug. Remove console. At this point you should be able to pull the front part of the headliner down around the front of the windshield. It will only drop about 2” to 3” which should be enough to carefully reach the wires.
Mount Lights
The side marker lights require 2 holes and the center light 5 holes IIRC. Take your time and measure everything twice to make sure you don’t drill any extra holes. You only have one chance.
Side lights:
On driver and passenger side, it is 4 1/4 inches from near edge of black rubber door rubber gasket to the near edge (side) of the roof marker lamp gasket 4 1/8” from near edge of black rubber windshield gasket to front edge of the roof marker lamp gasket
Center Light:
3 1/8 from near edge of black rubber windshield gasket to near edge of the center roof marker lamp gasket. Make sure you measure across to find center of roof and center light accordingly. IIRC, center is around 27 ΕΎ” measuring of the windshield top corner moldings. Place the lights at the approximate locations and place masking tape on roof so you can mark/drill without damaging the paint. It’s best to start with the center light so you’re not leaning over the outside lights during the installation process.
Measure all lights and mark holes. Once the lights are in place and measured, use a sharp tipped round scribe to mark the holes as you will need to place it down thru the light holes which are about 1” tall. This made marks on my tape which are visible once the lights are removed.
