i'm actually looking for a diesel version bonnet since those have hood scoops, but i want to keep the grille integrated in the bonnet because it looks better imo, haven't had any luck in finding any parts yet

I'd say forget about the oil temperature gauge & sensor, it's not going to give you any more information than you already have - an oil pressure on the other hand might be more informative.
Assuming a liquid cooled engine, coolant temperature is the best indicator of engine temperature, the lubricating oil takes longer to warm up & cool down, your engine could overheat and seize before the oil temperature even rose high enough for it to show on the gauge.
Back to the oil pressure gauge - oil pressure in an engine is like blood pressure in a human body, if it's too high you have a problem, if it's too low you have a problem, knowing that it is higher or lower than it should be allows you to take corrective action before it becomes a major problem - an oil pressure gauge will tell you if there is enough lubrication when the engine is hot.
See if you can find out how Ferrari officially recommends a grade of oil - I've been told it's whatever grade you need to give a specific oil pressure at a specific rpm point, in the conditions under which you would normally be operating the engine - it's a parallel to what I'm telling you here - the oil pressure is what's critical - too thin an oil for the temperature the pressure drops, too thick it increases

yeah the m13a doesn't have an oil temp sensor, but i'm having an aftermarket one installed and an indicator,

mh ok i understand, i'll still use the temp gauge, but i'll install a pressure one and a sensor as well, i'll check what ferrari says then 
thanks for the advice

thanks for the advice

I added an oil pressure gauge to my 1970s air cooled motorbike, they used to fit them as standard, but stopped a couple of years before my bike was made as when warm and at tick over the oil pressure drops to a worryingly low value. At mid range it’s about 55, at tick over it drops to less than 10.
So don’t be surprised if the same happens on your Jimny.

The Jimny WILL do something very similar, the challenge lies in knowing what is "normal" and what is "time-to-get-upset".
The FSM will tell you what the expected & acceptable pressure is.
