Is it the oil pressure sender perhaps?
On those 2 years (99-02 vs 03-07) the earlier one is a single wire and the later ones are 3 wires. Just replace the actual sensor to fit your plug. The threads are the same.

That's correct. The entire wiring systems are different for those year ranges.
Just get a 99-02 wiring harness. It's doesn't have to be a 6.0, a 4.8 or 5.3 will also work. Just make sure it's from a 1500 with a 4L60e and 4x2 if that's what your truck is.
For the computer, those other engine options will also work, but it would have to be reflashed for the correct engine you installed.

Yea this one has to be broken down simple for people to get it apparently.
For everyone here that needs to understand this:
99-EARLY 03 Engine Wiring Harness GOES INTO 99-EARLY 03 Truck ONLY
LATE 03 - EARLY 07 Engine Wiring Harness GOES INTO LATE 03 - EARLY 07 Truck ONLY
I think that should work...
