How to install a second stereo power supply?

Question

I am Trying to install a new stereo deck into my 85 Camry and I cant find the secondary power cable ( the one that keeps the deck in standby while the ignition is off so it can store the time and settings) I have come to the conclusion that my car doesnt have a second supply. And I was just wondering if anyone knew how to go ahead and make one ( i have an open spot on my fuse box) thanks for the help!

Answer 1

Use a test light,meter to find 12 volts in your fuse box thats hot with ignition off and make connection.

Answer 2

or u can run a wire off the hot side of your cigarette lighter its 12v and hot constantly and may be a shorter easier run.
