you need the power wire to go to constant power even with the key off you need power for that, that way you can use the memory function (save your radio presets). thats usually a yellow wire. then run the red power wire to the fuse panel in the stock radio location. that gives functioning power on accessory and run. i grounded mine to the dash speaker bracket on the firewall directly behind the head-unit.
