Are your fuse(s) on the radio circuit good?
And did the stereo that was in your car work before you pulled it?

On my '87 I had to ground the stereo under the dash to a metal support. Worth a try.

Sounds like you have  a blown fuse or a bad wire. Also you could tap into the lighter plugs power wire for the constant power source. That might be on the same fuse as the mem wire in the factory harness. I'm not sure but it might be.

im getting constant power... just no juice to the memory, none of my info is saved

every time i restart the car the radio goes back to its default settings

ya think a direct wire from the battery to the memory would work? or eould it run my battery dead?

Connected to what?
If you're using the original plugs, memory is green/yellow (always hot), main power (key-on only) is yellow/black. Both in the grey plug.

My thoughts exzactly master blaster. If you are really getting the constant power then your head unit would keep all your presets and the clock. Also why not just get power from the cig lighter. It is always on in these cars. Then you wouldn't have to run all the wire to the battery. And no it won't drain you battery to much. Where do you think the power comes from in the first place? Any how sounds like you need to check the fuses. Also some of those aftermarket harness adpaters are made cheaply and the pins like to come out real easy.

From the '84 EVTSM the "memory" is powered from fuse 8, which powers the "Courtesy Lamps". Glove box light, vanity mirror lights, trunk light, etc.
