switched gauge clusters now no oil pressure

[tazndrew04]

So it started out with me wanting to switch out the silver turbo gauge cluster for a black gauge cluster. The silver gauge cluster I had before the oil pressure was working, but since I swapped out clusters the one I swapped to the oil pressure does not rise. It stays down as though the car is still off. This is after letting the car warm up to temp. All of the other gauges work. I did not mess with any of the wires or anything having to deal with the oil pressure. Any thoughts on what may cause this different cluster to not register oil pressure?

Same thing happened to me...

I swapped a white faced cluster from my friends gst and my oil pressure gauge isnt working. My stock cluster was working fine when I swapped them.

I wonder if its a gst to awd difference or something?

The gauge in the new cluster could be..broken?

Off the top of my head, you could apply a small voltage, say, 3 volts or so, to whatever pin on the cluster is associated with the oil pressure and see if the needle moves?
