Foot Well Lighting

[Hoosier GXP]

For those wanting to add LED lighting to the foot well and tie them into the map light so they will dim out like the map lights here is a short tutorial for the proper connections. I have the standard mirror and have OnStar so if you have the same mirror these instructions will work for you. You do not need to install a relay with this setup. I used 9 inch led strips that have adhesive strips purchased from Advanced Auto.


Remove the sun visors and the pull down on the panel above the windshield it has metal clips that snap in. Once panel is down you will see a bundle of wiring running from the mirror. Gently peel back some of the binding and locate the "Gray" wire.

Be careful not to mistake it for a gray wire with a black stripe in it. Once wire is located use a wire connector like the one in picture. This wire is connected to the ground wire on the Led lights. I connected my wire here and fed it through the straps that hold the harness for the mirror


I then took small plastic ties and tied the new wire to the mirror harness so they will not rattle later when driving. I pulled down the side panel and fed the wire down and removed the side dash panel to access it.



I then went to the fuse panel on the passenger side and found a "hot" outlet that does not require the key to be on. I used slot #27 the interior lights 10amp fuse socket.



Using a fuse link I purchased at Auto Zone



I removed the center console and ran my wiring around to the passenger side fuse box.



Here is the wire connector I used to tap into the gray wire in the mirror harness.




I wired 2 led stripes and tested my setup and it worked perfect.

Nice Pictures and write up. Do you have pictures of the finished product? I would like to see that!

It's good to see you got this to work without any trouble. Nice write-up.

So when the lights are faded down by the computer, it cuts the ground and not the power?

Also, when you turn on a map light with one of the switches on the bottom of the mirror, do the footwell lights come on?

[BLK GXP]

I have mine wired the same way. Yes indeed the ground wire is the one that is switched, and sorry, but the new lights will not come on with the buttons on the mirror.

Thanks to BLK GXP here is a link to a thread where he posted his pic's of the lighting when he did his install mine look the same.

Ah yes, just another thing to add to my winter to-do list!

Excellent how-to-do-it! Thanks for the detail. Anxious to see it in person next time we meet.

Thanks for this mod. I used red LEDs. I installed it yesterday morning, finally nighttime arrived, it looks awesome.

Nice write-up, Glenn.

This can also be done without getting into the windscreen frame, since the grey wire you are tapping into originates in the BCM, pretty much right next door to where you made the power tap.

Thanks JR I will see if I can locate that wire and update the post with an pic of it's location.

[JRinKY]

It is pin A-10 in connector C3 on the BCM.

C3 is the big connector that sits horizontally just above the fuses.
The rows are A-D across the short side, and 1-12 in the long dimension.
D1 is the big pin in one corner.

You already know that its the grey wire, there are also grey wires in A4 and A5.

Nice! I'll try myself at it too.

Thanks for the infos!

I'm doing this this weekend. I'll look forward to your pic post and will also post pics of my install. I'll be tying in my windrestrictor to light up with the map lights and foot well too, plus I'm going to add a switch to turn them on without opening the door.

Great job Hoosier. One thing, you could have cut back the insulation to expose the wiring near the bottom of the A-Pillar instead of running the wires all the way up to the light.
