eonon 0821 in 2001 jeep tj

I have a unique issue, I just finished installing a Eonon 0821 in a 2001 Jeep Wrangler TJ this head unit is a DVD player, CD player Bluetooth enabled, IPOD enabled with a 5" TFT LCD Display built onto the face plate.  I used the factory wiring harness kit, however on the factory wire harness there are a dimmer and a dashlighting set of wires...  What do I hook those up too on the head unit?  I tried connecting them to the 12v switched ignition wire and everytime I turned the key to the aux position (or any position for that matter) the parking lights along with the dash lights would automatically turn on...  I then disconnected both of the wires (the dimmer and the dash light) and just left them aside.  Once I did this now the stereo will remain powered after I remove the key for several minutes, turning itself on and off!

I am so confused...  I am positive the rest of the wiring is correct it was really straight forward.  Please help, this is very frustrating...

I also get this god awful noise when the jeep is turned to the accessory position the stereo is on and playing then you close the door and the dome light fades off, as it fades off there is this feedback noise as it dimms down?!?!?

Any help would be very much appreciated!  Thanks Gary.
