Accessory wire no voltage

I'm installing a pioneer deck I took out of my last car into my car. Somebody really hacked this thing up and I have no idea what they did to it. All I can say is he must have had one hell of a stereo system. Anyways, I test voltage to the yellow wire that is supposed to be 12v when key is on ACC or ON, and I dont get significant voltage of any kind. I get good 13volts on the orange wire which is the always-powered memory wire, but not on the yellow wire. What gives? Is there supposed to be a fuse for this wire? I see a spot on the fuse block marked "radio" but there is nothing there and it doesnt look like it could fit a standard shaped fuse.

behind ur fuse panel u should be able to track down an accessory to tap into so that it is fused, or... u could go to your cig. lighter and tap into that, its on ignition and it is also fused, make sure u test it good with a voltmeter though cuz on my car when i honk the horn a fuse popped and my radio shut off...hope some of this helps

The spot labeled radio should be the spot for the fuse. Mike
