Update: Now with pics!

One momentary switch
a couple of short lengths of wire

Here is what the switch I used looked like:

Here is where connector X10170 is located

The picture is of the inside of the lower column cover (see the last 2 pictures to see this part back on the car). The slot in the middle is where the steering wheel tilt lever comes through. The "test hole" is my first attempt. There was not enough clearance. Doh! For the second attempt I drilled into a location near the Styrofoam padding. The padding can be drilled into or cut back as needed.

This picture shows the wires used in both the multi-function retrofit and the button relocation. The green connector plug is pulled (X10170) out. One wire from ///Momentary switch is run to the ground wire in this connector. The other wire is connected to the DSC wire. The DSC wire used to be connected to pin 8. I disconnected it when I did the multi-function upgrade.

I used a couple of crimp-on quick disconnects so I can take the trim piece off without clipping wires. A squeeze tap-in connector was used on the ground wire.

Front view of the button.

Side view of completed project. There is a piece of electrical tape over the extra hole and it hides it pretty well.
