I have a 1998 ford f150 4 wheel drive. We put a new radio in it and now my reverse lights don't work. They work before we changed radio. Any advice

 

I moved your post into the Electrical section, Marsha. You should get better help here.

Have you checked the fuse for the backup lights? You should be able to find out which one it is if you look in your Owner's Manual.
