Another wiring question.

[B 4 You]

So, power mode is successful. I have a nice pushbutton switch tucked away somewhere, but it's bothering me that I don't have a real place for it. I had an idea though, but I didn't do it for fear of breaking something. The parking lights switch. It's in a perfect, discreet location, and wouldn't require adding any holes (my biggest fear). Can I simply connect my power mode switch to the terminals of the parking lights switch? In theory, when the button is pushed, the parking lights and power mode will both come on. Will this have any negative effects on the car? It's probably a stupid question, but I'm afraid connecting the ecu to another input of voltage will confuse or damage it. If I don't, I'll just disconnect the parking lights switch and rewire it to house my power mode switch.

PS, if someone has an image of the switch from the back so I know which terminals are power, which are lights, etc. that would be fantastic!
