I am installing a Pioneer Deh-1200MP inside my 2000 toyota Corolla. I matched up all the colors to the harness I bought and was left with a Blue with white wire(Remote Control access) on the harness that connects to the stereo. And there is a blue wire and an orange wire on the other end of the harness so I left the disconnected. When I installed my new head unit in it did not want to turn on and then I noticed that my Clock that is in my car(not the stereo) does not turn on either which it did before. I checked the fuse and even replaced it thinking that would solve my problem but nothing. So my stereo is not working and my car digital clock stoped working. What can it be if it is not the fuse. Maybe I need to connect the blue wire to the blue and white wire? What please and thank you.
There's two fuses. One is for the switched 12 volts to turn the radio on when you turn on the ignition switch. The other one is for the station presets and the clock memory circuit that stays live all the time. That one will be tied in with something else that is always live such as the horn, interior lights, or brake lights.
