I have a kenwood stereo on my 1987 mustang 5.0 convertible and when i program the stereo with the time and everything and i turn the key everything erases and it goes back to standby mode and all my proggraming is erased.
Please help me with this problem because i cant start my car and continue listening to my music from were it las left off!

 

You have the yellow and red wire mixed up or both wired to the same switched circuit. Yellow is Acc (Switched) and red is full time Powa! (Fused full time power)

 

I know this might sound stupid but its my first time wiring a stereo and where dose the acc wire goe with the chassis or whatever and is there any picture you can get for me because the problem with my vert was that it was stolen along time ago and the stereo harness wires were cut so i dont know were the wires go!!

 

I noticed i have a wire which is marked as "ant cont" that is not wired to any other wires so would this be the problem to my settings not being saved?..

 

that is to power the power antenna, which you do not have. It has nothing to do with your memory settings but you will need to insulate it to make sure it does not ground out.

There are three power wires needed for the radio.

Yellow +12v constant. This wire will have +12v on it all the time no matter what position the key is in.
Red +12v switched. This wire has +12v on it when the key is on, and show as a ground when the key is off. It has nothing to do with the chassis.
Ground - this goes to the chassis and has a ground on it at all time.

I agree with him that you either have you yellow and red wired to a +12v switched wire, or you have these two wires backwards
