oil temp and oil pressure gauge on 12v
 

i have a 96 cummins i ordered glowshift gauges for it and i ordered oil temp and oil pressure now glowshift offers a oil adapter to run both into one fitting but the thing wont screw on to where my oil filter goes so what im wondering is how can i hook these up with out tapping my pan maybe stock sending unit what do yall recommend thanks

there should be two nipples on top
of the filter housing. 1 is occupied
by the factory plumbing, the other
one is plugged. thats the one you
use.

On the oil housing?

yes, on top of the housing.

Anybody got any pics of what I need to do
