Ok, I have a 02 and got a smoking deal on an EZ chip for an 01... The plugs for the MAP sensors are different. It looked like the wires on both were the same. Are the MAP sensors internally different or just the plugs?

 

Just the plugs, to my knowledge.

So looks like buying two of these: Map Sensor Adapter Harness (3104228)
Map sensor harness required for 2002 Dodge

and I am in good to go.

 

Should be set to rock!

 

Nope.... Need one wire harness and the 01 map sensor, I believe...
