Where is the rear def button and the trac control button on the 99 mustangs? I have an 02 and they are below the radio but Im looking at putting in a 99 radio trim piece and notices the buttons are not there. Pics would be nice as well if there are some out there

 

I would check the manual...

 

i used to have a 99 the rear defroster is below the headlight **** and the trac control is i believe where the cig lighter is at in a 99
