G-Body Factory Gauges
I swapped out the idiot light dash on my '86 El Camino with a Monte Carlo factory gauge dash. It was fairly straight forward. Everything worked, however the oil pressure gauge pegged way over 60 lbs at idle! I disconnected the sending unit to prevent damage.
My question is: Are there two different sending units; one for lights and one for gauges? I'm also now wondering if the water temp is different. I know it was when I put factory gauges in my '67.
PS - Does anyone know a source for tach filters? Mine has has a very iffy wire.

for an idiot light the sender would have to be an on/off type switch it would close after a predetermined pressure drop to make the light come on
check the parts store to see if they call for the same sender , if there different changing it should solve your problem. if there the same you could have a short in the wiring, in order to get your guage to read acurately you need some type of variable resistor with it i would think that would be part of the guage? i know a few guys were talking about the same swap a while back maybe they have some info. :cool:
