I've spent a bit of time researching your problem on the ordinary internet and have found feck all really.
I expect the tacho will need a connection to the road speed indicator connection to the OBD2, but I don't know which one that is. Maybe your mate knows.
I hate electronics altho i am having to learn 'em as the wretched vehicle seems to spend a lot of its time thinking up new electronic problems.
I'm fine with mechanical stuff!
I wonder if @sierrafery might know as he is the whizz on D2s and especially the electronix.

I know right? Pain in the butt!
This aside, I have a door actuator that locks but doesn't unlock, a window lock switch that doesn't, a rear window that works both ways on the rear switch and only down on the front switch... grrrr!

Dare I ask why you need a tacho? Have you also got to do a DCPC?

I need a tachograph because my train weight is over 3.5t and it's not for personal use. I don't need a DCPC because it's not a bus, coach or lorry and because I am not a professional driver.
