Can you tee off the oil sending unit to run an oil pressure gage and still keep the idiot light working on a 1969 Plymouth roadrunner with a 440.

The 440 in my RR had two tapped oil provisions. 1/8" NPT IIRC. Not mine - a pic I grabbed off of the devilweb.

That's how I did mine (383). I didn't know about the other port at the time.
