i need a wiring diagram for a 93 jeep wrangler(stereo)?

Question

mainly the ignition wire and the memory wire

Answer 1

Dang now I know why you are asking for help... what a mess.

Orange/white and Orange control your lighting. I would say try to hook the dimmer wire to Orange since Orange/white should be on when the ignition is on.

Red is your switched (to ignition)
Pink is your memory or constant

Now there is no ground in the plug. So splice into the ground wire that went to the back of the factory radio.

Good luck
