Yamaha F250 4,2 offshore pics water pressure kit/speed sensor

[Bertram31SF]

Got my new Yamaha 4,2 offshore F250 engine on a Boston Whaler 21 outrage incl.6Y9 Display.... more than happy.
But must manage some things:

1.)the speed display doesnīt work.Is the speed sensor kit not installed from new?Does anybody has a pic or something like that to see the location of the speed sensor?

2.)I want to install the water pressure kit too.Does anybody have pics of the location ?

My dealer gave me this kit number:63P-8A4L0-00 on the Yamaha side itīs starts instead of 63P with69J.
Could i take both?Whatīs the diffrence?

look here:
Yamaha OEM Parts ? Outboards, Outboard Motors

3.)There is a wire with two cables (blue and white) left on the 6Y9 Display.I think itīs GPS .How could I connect it correct??(to my northstar GPS???)

Thanx
Nico

Here in the USA the part numbers are
69J-8A4L0-11-00 Water Pressure Sensor kit
60V-8A4L1-11-00 Speed Sensor Kit
Don't know what part numbers would be on International motors.
Water pressure port is back on engine,
WaterPressurePort 4.2L.pdf
Water pressure connects harness with "W" on connector, Speed sensor connects "S" connector.
The White wire could be connected to NMEA 0183 positive output lead of GPS and Black to negative output lead of GPS so Display unit with display GPS speed.
