Bill,
I did exactly that. The manifold has space for 2 sensors and normally one of those ports is just plugged. A pressure switch (like used for a hobbs) in that port will drive a light just fine if the concern is an oil pressure indicator independent of the EIS.

Bill, if you have a an oil pressure switch (not pressure transducer) that you are using to run the hobbs meter, you can also wire that to a separate light. You should wire it to a bus powered when the battery contactor is closed. That way, you know oil pressure (good/bad) separately from the EIS.
On a related note, I do have a 1" UMA oil pressure gauge mounted on the panel and it uses a separate pressure transducer than the one driving the EIS. I normally don't think that duplicate engine gauges are necessary, but in the case of oil pressure, it is the one instrument IMO that can drive some hard decisions if it or the transducer fails, so I have two separate ones.
