..

Only two wires.

bad switch

If the radio plays with the engine off but not with the engine on then it's an electrical problem that a new radio probably won't solve.

If you need further help, I’m available over the phone at https://www.6ya.com/expert/oscar_403cc49e0f00cda7

These details will help you thanks.

Thanks for using FixYa.

I would inspect your wires at the starter. If you live up north then corrosion is bad, clean all wires going to starter. then clean wires to back of alternator. I seriously doubt that alternator is the problem, but if you remove it you can have it tested for free at most parts stores.

check the wiring harness beside the hinge that moves when you close the trunk.i have seen the wiring get pinched and the ground gets broken. the tail lights have separate left and right side fuses.get a test light,and with the ignition in the on position,there should be power on both sides of all the fuses.the atc type have little test pins on them.ground the test light and put the tip on the fuse.if there is power,the light will come on. if a fuse does not light up the light on both sides,it is open.since the fuses are see thru,it is apparent if it is blown as the metal inside will be burnt.

this is best left to a professional front end shop, it requires expensive special tools, if u still want to do it let me know and I will give u the tools needed and instruction u need to proceed.
