94 Gt Rear defroster wiring?

Hmmmm...I test drove a convertible gt 95 (before I bought my current one) yrs ago, and it didnt have a rear defroster. It didn't have the lines in the rear winshield for defrost. I don't know if they used the same rear windo on defrost and non defrost hard top cars but it cost much more for rear defrost windows so I would assume the rear non-defrost hard top windows wouldent have lines either. In you case maybe somebody broke your rear and it was replaced with a junk yard rear from a car with a defroster Only thing I can think of. Someone with a no rear defrost hardtop will chime in hopefully.

i have a 94 hardtop that didnt come factory with a rear defogger window. but i bought the switch from my local ford dealer and a rear windshield with a defogger grid in it from a junkyard......and now i have defrost. my car had all the wiring. its the same with fog lights. hook up a switch, lights, and a realay and your good to go. hope that helps
