I'm trying to wire a radio into a 2000 Civic SI for my friend, but I'm running into a problem. The previous owner hacked and spliced up the original adapter so I was following the audio diagram. Everything is hooked up, but when you turn the car off, it will not remember the radio's settings. Now I know you have to use the 12v constant power wire, which is the blue and white wire. But there is no power going to the 12v constant wire coming from the car. I can't find any wire that has constant power, I used a multimeter and tested every wire except the obvious speaker wires. Any help would be great, thanks.
