Radio not working

[Fordy nine]

My kid took out the JBL CD Radio and put an aftermarket stereo, and that got stolen. I put the JBL back in yesterday and just plugged in all the connections but it dosent come on. The lights work when the dsh lights come on but no radio.

Anybody know why it wont work?
