Most factory chrysler head units from the 90's already have a wireing label sticker on them..... tells you which wire in the plug goes to what. Of course that only helps if you had a stock radio to begin with.....

That 12volt site is nice... Thanks for the link. I'll be putting a new HU in my 96 in the next few months.

Does having the Infinity system affect choice in HU? Due to it using a different amount of Ohm resistance?

The infinity amp that is under your rear seat requires both power AND ground connections to be made behind your head unit. The reason is to prevent ground loop problems (noise and hum) from entering the system. Make sure you have the remote power lead from the amp connected to the remote trigger wire from your new head unit (not the power antenna lead) but the remote trigger lead. Also make sure the neg wire that was clipped to the back of your factory infinity stereo is now connected to both the ground of your new deck as well as earth (dash) ground. That should get the music flowin in your jeep!!

ok i got it working!i didnt have to bypass the amp or anything like that. i really made it more difficult then it needed to be. on my old factory stereo there was the wiring diagram and i double checked my wiring with it today. i found i had mixed up 2 of the wires and run the antenna to a speaker. so now my radio works, antenna goes up and down, however my deck wont play my ipod when its connected to the usb or the aux port. the visualizer works when i have it connected to the usb or aux, however the visualizer also worked on radio when i had my antenna hook up to a speaker.
any ideas? it puts out sounds on radio only. not cd, aux or usb

Darman, did you ever get this figured out? I've got the exact same problems with my spanking new Pioneer HU w/ Ipod control. I only have radio, nothing else.

Gotcha!

I finally figured out my problem late last night after monkeying with it for quite a few hours.
