I am installing a radio in an older car 85 Nissan pickup. I can not find a constant 12v wire (yellow). There is a red wire which i assume is an ignition wire. But both of these wires the yellow and red only see 12v when the key is turned on.
Is it ok if if i connect the red and yellow wire together?
Is having a constant 12v wire to the radio necessary? If i dont will my radio settings always get erased when i turn off the car?
