Wouldn't it work by just splicing the fog light wire into another under the dash instead? Wire the fog light with another wire that is "on" when ever the car is not just when the head lights are on?
For those of you that have installed a double din.
Do you miss being able to see the current mpg, miles remaining, etc...?
I have a double din from a previous car that I'd like to install but I really like being able to see the info.
Your inputs are appreciated.
