adding oil pressure and temp gauges to Yanmar 4JH4 engine

[Mike Wilson]

My 2009 B40 has the "reduced footprint" Yanmar panel without the oil and temp gauge.  When I look at the engine on the oil filter side, there are a couple of factory connectors that I do not know what they would connect too.  They are in the are where I think the sensors are.  Has anyone investigated a method to get actual readouts?  Not sure if the sensors are there and only need to connect to gauges some place off the panel or if the sensors would have to be replaced.
