Dumb question but where did you plug it into under the dash?? Could you get a longer wire and run it to the rear of the vehicle and have a 12v there also?
Thanks
There is a 12V outlet under the dash on the passenger side. Closer to the door. Take a look.
And I guess yes. Why not. But I would go with the suggestion posted above if you're looking for a more permanent solution.
Be careful with the positive and negative side.
