This F250 is so much more of a pain than my F150.

I have a 95 f250 5.8 L 351. Where is the switch???? My gauge reads 0 on oil pressure, and actually goes lower when the truck is started. logic tells me to start here, BUT WHERE IS IT??????????????

 

Found it. Pretty much the same as my F150. Right above the oil filter. Do not know why I could not see it.
