Forget oil TEMPERATURE only racers need worry about it.
How can you say the temperature sender is simple when it supplies a graduated scale, and the oil pressure switch is difficult when it is an on/off switch set to 'go' at a given pressure ?
The tolerences within the engine are very fine so it is not inconceivable there will be residual pressure, in a stop /start situation!.
There is no conceivably situation where installing an oil pressure gauge will be detrimental to your vehicle (unless you f**k up the installation)
I was just making sure that the connection was the RIGHT kind

which will make sure I don't get it wrong.
Temperature is simple since it moves as you say in graduation where as a switch by nature of its construction appears simple but can stick.
I was thinking out loud as far as the stop start thing. If you start your engine from cold then sure the light will come up as you turn the key but if you were to stop 10-15mins later the light might not come on since there is residual pressure, that is what I meant by it starting to make sense.
This is beginning now to appear to be a simple bolt on job, it is the descriptions of various gauges that is now the problem

that and knowing which size to go for, but that will be pod size dependant as I didn't like the way Guy88 had mounted his.
Adding the picture in case others have not seen it
To Guy88 (who I am sure is still reading this and wondering what daft question I will ask next

) Now you have the Amby pod, which had a replacement plate anyway, I would have mounted all 3 gauges in that and ran switches from the stock postions around the instrument cluster. Ok that is just me but thought I would say it, before someone posted up that who cares where something gets mounted. I have recently replaced my dash and no way am I putting any holes in it that weren't already there. Plus mine is a MK5 so the Pod option is a no go for me anyway.
