On the 2002 Dodge Caravan there where 2 different wiring harnesses and 2 different radio styles. One style was a am/fm radio with a casette player, and the other was an am/fm radio with a cd player. I'm trying to change the casette player to the cd player that was installed within the same year. The players were put in during the same year they just upgraded after a certain month in the year. The casette player has 16 different wires to the wireing harness that plugs into the back of the stereo, and the cd player harness only has 14 wires. Also none of the colors match the harness for the cd player. I need to know what wires I need to hook up to the cd player ,from the harness from the casette player. Can you tell me what wires go where so I don't have to worry about it not working, or hooking up the speaker wires backwords?

Re: WIRING CHANGE FOR 2002 DODGE CARAVAN
Your best bet on that one is to go to a place that sells car audio systems or even some autoparts retailers have them,and get the proper adapter harness already made up. A few more dollars but, a whole lot less headaches.

Yes, go to the dealer for a a ECU update with the radio's data. If you had gotten an older radio, cassette,cd player it wouldn't require reprogramming. Best solution is to buy a new unit from Crutchfield on-line and don't forget the wiring harness and faceplate adapters. Some allowing steering wheel control and IPhone/IPad connection.
First set park brake,locate PCM in van ...Compare new PCM with old to be sure new one is correct part..You will small tube of dielectric lube..WEAR SAFETY GLASSES..,Disconnect negative battery cable...wipe and blow dust/contamination from around wiring harness plugs...Remove plugs from PCM...,Remove old PCM..lightly lube connecter pins with cotton swab..,plug in wiring harness connectors..re-connect battery cable...Complete..............BROOKS..
engine wiring harness problem. look for large connector at drivers side of intake manifold.wiring to the fuel injectors decay and short to the other wires [a.k.a. ac hi psi switch] backfeeding voltage to ac,engine sensors. will result if unchecked in major computer and wiring harness failure.
Is the car running okay.
Then don't worry about it.
Dodge makes the same wiring harness for several different engines. The extra connector most likely is to meet the california and other states strict emmission standards for an additional sensor or different location on the engine the same sensor that is connected now.
If your installing a stock radio/cd player from another Dodge the wiring plug is the same and will fit.If your installing a aftermarket radio/cd player(JVC,Pioneer,etc)you will need to buy a adapter plug that wires up to the radio and is a direct fit to your factory wire harness,so your not cutting your wires.When you buy the adapter plug it comes with a wire diagram of which wire is what.Your aftermarket radio should have a diagram also,either on it or in the manual.Hope this helps you.
Although the transmission may be siilar, the engine and supporting wiring harness, and control modules are not. This can be done, anything can, but it is probably more trouble than it's worth for a mini van. If this was a classic car then sure.
