I recently installed a new radio in my car and every time you stepped on the break it would turn off the radio. I couldn't find a screw to hold the ground wire down so it would be contacting the metal so i initially taped it down with electrical tape.

My car has 180000 miles.
My car has an automatic transmission.

Hi there. The ground wire should not have anything to do with applying the brake unless the wire is coming in contact with the brake pedal assembly causing poor contact when using the brakes.

Make sure that the connection is also clear of any paint as that will impede the connection.
