I had your problem.I think there are a few different styles of MAPs and i'm pretty sure I couldn't find that one either. I got a different P/N than yours for my 02 2500. The replacement map sensor P/N I got for my 02 was a Cummins PN 4921505. You can find it here @ Genos- .Dodge Cummins Diesel and Ram 1500 EcoDiesel Parts & Accessories. Call us at 770-886-2500. Then I called Quadzilla and had them send me the correct MAP connector harness.
