Dash, Odometer etc

2000 Volvo s40

Is there anyway to tap into the wiring behind the analogue
Odometer,Speedo, Oil Temp, Fuel level, and use the signals as an input to
a digital display?

Is this the kind of thing that the Haynes Manual could help with?

I would be hard pressed to believe that a Haynes manual would help there;
I find them rather useless for anything other than basic tune up and
capacity information...

Perhaps the manufacturer of such instruments would be a better reference,
but I must ask: Why would one do this? I personally prefer the look of
analog instrumentation, and (thinking of late 80s Ford products here)
digital dashes tend to be somewhat troublesome. And I would imagine this
will cause you trouble with your warranty.

Lots of guys there have done just about everything imaginable to their cars.
Someone in there will have an answer for you.

This would be really tricky on an S40, as the analog instruments are all
electronic and if it's anything like the other late model Volvos they all
interface to the main computer, so you'd have to hack the protocol and build
a microcontroller based box to interface to it. Definitly not Haynes manual
material, this would require some serious work, something like installing a
state of the art fuel injected engine from one car into another car of
completely different manufacture.
