I've been reading & searching since I bought my 99 last week; and my oil gauge sits at 0 for a few minutes after starting (it has been below freezing since day 2 of owning the truck)
Apparently there is a mod where you can put a oil pressure sender on instead of a switch; but I can't find a part # that I can pickup at Oreilley or Autozone.
Also it looks like no resistor to jumper on the 99 either; simply swap the sender and voila a real gauge, is this all correct?
This is the best writeup I could find: "Dummy" Gauge
Thanks for any help
