Dave, follow the red flasher wire here with katfish's post above. a test light should light up. if not, follow it to your radio power wire. Test light should light up. If not. follow the black wire right to the fuse box. Does your radio work? Same fuse.
I've seen the contacts that touch the fuse have to be cleaned sometimes to get power. the fuse lights the test light but the side contacts do not.
If you still can't get it, I will fix it for you on Friday. I can fix anything electrical.
