Trying to get my car safe to drive

In the vicinity of the ash tray, there should be a connector with an orange and a white wire in it. This is the connector for the radio. I don't recall which wire controls what function. One powers the dial light and is switched by the headlight switch and dimmer. The other is power for the radio proper. It is hot when the key is in the ON or ACC position. The lone red wire is for the lighter and is always hot.
