The above picture is the wiring harness for Dodge vehicles over 2001.  Maybe this will help you figure it out.

If you give me the year of the vehicle and whether it is Infinity system or not I can give you a better answer.

But, in general, you must know what the requirements are for the wiring harness conversion for an alternate system.  The deluxe system used in the Durango is Infinity and it takes a different wiring harness from the regular or aftermarket products.

Let me know more what you are doing and I will reply, again.
