Gauges dont work after new cd player install

FYI if you remove the factory unit it will disable the cars starter and or fuel pump. The radio is tied into the security system. You shoud be able to get the wiring color codes here:

Did you have a new key cut using a blank that matches the old chip ?

no dont cut wires

This is a website you can go to find wire color codes for your vehicle. http://www.modifiedlife.com

Im quessing you are trying to install a sony radio into your jeep. The question is do you still have a plug on the wires in the dash? Or has the plug been cut off? If you still have the plug-you can buy a wire harness from Best Buy or Crutchfield or any car stereo shop that will match the wires for you. If you need more info on how to install this radio without the harness, e-mail me cuz it's alot of typing for nothing if you don't.

I am not sure about repairing the unit. Do you have a CD cleaner?
You might check with a reputable auto electronics shop, one that specializes in car audio. They may have an adapter that will allow an aftermarket radio to be controlled from the steering wheel. Rosen makes a nice am/fm/cd/dvd navigation unit that also has XM and iPod inputs. The hard part will be to find supporting interfaces and wiring harnesses to fit a 99.

you normally have to get codes from the dealership

you may of pinched or cut a wire while installing the cd player. or possibly when hooking up to power, you plugged into the power for the instrument cluster

go to walmart find your cd player, dash kit ,wiring kit and then this is what you do .. remove the old radio attach the wiring harnes you bought to the factory wiring harnes this will allow you to match the color code up for your new radio with out cuting wires then install the new dash kit witch will allow you to install your cd player with a factory look this should be everything ou need to know
