You have two power feeds for the radio. One is switched by the ignition switch and the other is "hot" all the time. The power feed that's hot all the time is for the clock and radio station presets. Go back and test your power feeds for the radio and see which one is always on and which one turns on and off with the ignition switch. Then refer to your new radio's wiring diagrams and see which power feed needs to go where. HTH. -Jim


So you are saying go see which wire is the turn on and off wire and which is the turn on and off wire for the new radio wires and put them together and yes the presents and clock save so I know that’s good

Yes, you're on the right track. There should be two power (+) connections on the new radio. One should be identified as being switched and the other hot or live all the time. HTH. -Jim
