Instruments on Nanni diesel motor

[benchmark]

Hello and greetings from Copenhagen Denmark, thanks for allowing me unto your forum.

I own an Ocqueteau 815 with a Nanni 4.390 motor and while doing some installations recently i noticed that the electrical loom form the motor up to the overhead instruments have some extra free sockets that are also wired but non utilized. i am wondering if anyone knows if or what instruments i can possibly but and plug in the the vacant sockets that can maybe give me more information from the engine.

i will try to attach a picture to illustrate what i mean.

Also, does anyone know if its it possible to extract information about fuel economy for the motor ?...e.g liters/nm?

Welcome Benchmark, are you sure they are not duplicates for the flybridge?

I did not think of that, you may be right. i just wanted to be sure that there are no other possibilities that i am overlooking.

i just noticed that the sockets in the wire harness that comes from the engine to the dashboard instruments are labelled with letters and i wonder if this may further give a clue to what these unused sockets in the wire harness can be for

The electrical harness has a wire socket labeled
'V' which is connected to the Voltmeter gauge.
'P' is connected to the oil Pressure gauge.
'T' is connected to the Thermometer gauge.

I have 2 extra wire sockets labelled 'F' and 'C' which are unused and i will like to know if i can connect any more gauges to them to relay more information form the engine but i need to know what they are originally meant for.

Can the 'F' socket be for a Flowmeter/Fuel economy gauge?


The engine is a Nanni Diesel 4.390 , 200hp from 2007 .

here is a picture that shows the labeling to illustrate what i mean
