Thanks for the replies. I will run a switch from a 12v source, and its a pontiac sunfire with the weird wire harness that requires me to keep the stock head unit in the car for various functions.

First time poster and am wondering what is the signal that the D3 needs to activate its night mode. My vehicle has a messed up wiring harness that has no illumination wire and I am wondering if a simple +12V or a ground signal to that wire on a switch will activate the darker background. Thanks for any answers.
