i own a 1997 explorer eddie bauer edition and i want to install an FM modulation relay. i went to install it the other day and pulled the radio out but there was no antenna plug or jack in the back of the unit and i need to know where the antenna connection is. any advice would be great thanks.

I would follow it back from the radio. Check right behind the glove compartment. It might be there. That is where one is on my Mustang, but it is an 06 so no telling. Hopefully they keep the same methods.
