My wife and I just bought an1988 aerostar as a second vehicle and it runs great but it has the Premium Sound in it and I am at a loss. The factory amp was bad so I replaced it with another from a 90 aerostar and I can't get power to the EQ and my speakers won't even play static. I did the pop test on them and they are fine. Does anyone know where to d/l the wiring diagrams? I know this is an old vehicle but I'm hoping someone has some ideas.


Thanks in advance
