Couldn't find a thread here for footwell lighting so I figured I would start one.
All the connections can be made in the footwell on the passenger side. No need to run wires to the rear view mirror.

The LEDs that I purchased are available at Oznium.com. Each module uses 6 PLCC-2 style surface mount LEDs with a wide 110 degree viewing angle so you don't get any hot spots on the floor. They are very tiny and will fit any where. This one on the driver side is mounted under the small hump under the OBDII connector.

I purchased the LED modules here.
http://www.oznium.com/led-modulesYou will require an "Add-A-Circuit" mini from Littelfuse to tap into the fuse that from the factory powers the interior lights. Be sure to get the "mini" version. You can pick them up at any auto parts store. I have purchased them at both Autozone in the U.S. and Canadian Tire in Canada.

The hook up is extremely simple and with the wires connected as in the above picture the LEDs will turn off and fade with the rear view mirror. The completed installation with the Add-A-Circuit in place would look something like this. The LEDs are on the add-a-circuit on the right. The add-a-circuit on the left is for the switched power for my HHR rear view mirror.

Finally when all is said and done the LEDs look great and it's amazing how much light you get from these little modules. You can see one of the maplights from the rear view mirror at the top of the picture and of course the footwell lighting.

I am very happy the way it turned out and I may soon be looking for more places to put LEDs.
