okay i have this 2001 dodge cummins and a guy took the 24 valve out and put a 12 valve in here and i want to no if i can take the oil presher sinsre out of the 12valve and put a 2001 oil presher sinser in there

no - I believe you need an oil pressure sensor from a 12V.

will i have a 24 valve wiring harniss

the sensor for the 24 valve will plug into ur harness, it is probably different plug in than the 12valve one

will the sensor from a 24 scrow in to a 12 valve block
