I was wondering if it is possible to put mechinical gauges for the oil, water etc.. without messing with the computer and or mess with the way my truck runs or if there is a way to T off the oil line so the dash guage still reads but i get the actual oil pressure in the cab its a 2004 f150 2wd 4.6

 

Look at my post here, should be about the same for you
