VP37 signal characters

[svenakela]

Does anyone have knowledge about the signal characters, both in and out, for a VP37?
I would like to know how to read/drive these:
The Quantity adjuster (N146)
Modulating piston movement sender (G149)
Fuel temp sender (G149)

Unfortunately I have no ECU so I can't hook up an instrument to see what happens. I hope someone else already did that.
