Hi Martin,
I got a D1-30 and there is no place for a 2nd Temperature sender nor for an Oil pressure sender.
So I'm guessing we're stuck with VP temp gauge. Bright side, is that it's easy install as the cabling is std CAM plug'n play.
If someone else found a 'hole' that you can plug another temp sender, I too want to know.
Also, don't you have a problem with that stupid alarm buzzer? Can you hear it?
this will set you back lots of bears as well - Eur150 for Y-splitter and alarm that can be heard and installed anywhere you want it.
R,
Hratch
