I have a 2006 Pacifica Touring 3.5 Litre 2WD. I hit a deer and tore off the upstream connector end of the secondary oxygen sensor wire harness. What I need to know is if a 2004 Chrysler Pacifica uses the same 4 color coded wires and connector as the 2006 model I own. Please advise.

 

buy a repair kit from Chrysler

 

Take a look here. It is a listing of Mopar wiring repair kits. For what it is worth it looks like the same kit is called for from '04-'07. I would check with your local dealer for a price on the kit and for a cross reference however.
