My left button is wired to a garage door opener which is tucked away inside the center console. The middle button operates my footwell lighting. The right button is a dummy until I think of something.
I originally just planned on hooking my footwell lighting up to the Z kick plates on each door. That works fine. But then I wanted to put in a switch to control them just like my dome light (On-Off-Door). The problem is that the Z kick plates are controlled by the ground wire of the kick plates. The power wire always has 12V on it from the battery. My first thought was to put my switch on the ground side, but then it would be possible to accidentally leave the footwell lighting on even when the key is removed. Long story short, I used the circuit shown in the attached pic, which switches between two circuits:
Forward (ON): Accessory 12V power and Chassis ground
Middle (OFF): Both circuits open so no footwell lights at all
Back (DOOR): Z Kick plate 12V power and Z kick plate ground
I normally leave it so it turns on with the dome light, but sometimes I put it on while I drive in rice mode.
