For the memory wire, just plug it in to the power side of an open, non ignition controlled spot in the fuse panel.

Blue wire is usually the power antenna on aftermarket radio.  Usually the + for the memory is red.  You can splice it into the orange wire going to the cigarette lighter and be done with it.

Look for the "dome" fuse. Its blown.

I would use a test light at the fuse panel and see if you have an open B+ port and run a new FUSED wire to the radio. You will get B+ from the cigarette lighter but I would run it seperately if you can. I had a radio hooked up through the cigarette lighter once and I plugged in a small power inverter and it fried the deck.

Replace the dome fuse. Just because it doesnt look blown doesnt mean it isnt. Just double check ig
