Help with stereo wiring?

Hey guys just bought a 1999 Sahara with 133k on it. She needs some work and I'm looking forward to getting her on the road before summer. Well while waiting for parts to come in I decided to put a new stereo in, which I have done to many vehicles before but I ran into some issues with this one. I noticed that every time the key was switched off my odometer trip and radio settings would reset. So i replaced the head unit last night and in order for it to power on I need to connect the constant and ignition power wires behind the head unit. And still whenever the key is turned off the radio looses its settings. Another weird issue is, without the radios ignition and constant connected the odometer and gauges do not work on the dash.

Everything works when I have the red and yellow (constant and ignition wires) connected behind the head unit though!

Any thoughts?

Thanks in advance guys

Alright guys I made a fix if anyone else ever has this problem. I just didn't have a constant running obviously because my radio did not have memory. What I did was run a wire from the 15 amp auxiliary fuse to the yellow 12v constant and we are all good now. Let me know if you guys have any other ideas.

The pink wire with the white stripe is you constant 12v wire. If that wire has no current replace the fuse in your fuse box. The pink wire is your 12v ignition. both these wires are on the stereo harness. If they were cut then someone probably cut the whole harness at once and blew the fuse.
