Ok than tried to replace the old dome light with a Mustang one and it work for a min than did not so i put the old unit bacj in but that one does not work now ether. With it getting dark out last night i gave up till today an noticed my air bag light is blinking a code 2 than 9.My guess would be a fuse but cant find it.
Any ides what the code means and what fuse would tie into the dome light

 

got it fixed now

 

Was it the fuse?

 

Fuse?

 

I did the same thing when I went to install mine. I blew a fuse and the speedo wouldn't work either. Don't remember what fuse it was, but it's not hard to figure out by looking at the owners manual.
