aftermarket stereo ?

[93star]

hi i have a 93 ford aerostar and i recently installed a stereo,i was wondering is there a memory wire avaliable for these,i hooked up the wire that controls the speedo and odometer to constant power and the light dimmer i left off,i even tried to connect the aux wire on the deck to constant power to see that would work for the memory,i know the head unit has a memory function cuz i pulled it out of my truck,so any help would be greatly appreciated,thank you

why would you have your stereo hooked to a constant connection? Just hook the stereo to the old stock hook-uops and you should be fine... What make and model is the deck?
