on my d16 engine.. i removed the stock oil pressure sending unit and put in the line for my mechanical oil pressure guage. I just left the wire hanging and i never threw codes or the light never came on

when i get my b16.. do i need to keep the stock sending unit so the computer knows there is pressure for vtec or is there a separate one for that?

also.. if i do need to keep the stock one.. can i just wire it to ground.. or 12V+ to trick it into thinking it's at correct pressure

i really don't care about the light still working.. i'd rather have my mechanical guage.. i always pay lots of attention to that guage.
