Every time i turn my truck off the equilizer resets

The signal light switch on the steering column actibvated by the turn signal stick probably needs replacing.

Do you have tweeters in this model, and do they work?

Thanks for using FixYa.

u do not have a fuel pump reset switch...fuel pump might be out

Go by a stereo shop and get an adapter for your car. It connects all of the correct wires to the aftermarket radio without damaging or removing wires from old connector.

remove center console lower wood and switches, remove ash tray, remove 2 screws to remove ash tray unit. Pop off face of radio, push in plastic tabs holding radio in console and pull unit out.
