What speedo options are there for an 850...

Once the abs has been removed?
I gather the Volvo unit won't work, so I've been looking at gps units.
Any way of setting up analogue?

95/96. On an N plate but can't remember exactly without looking.

obd 2 takes the speedo reading from the Gearbox. so doesnt matter if you do away with the abs

obd1 gets it`s signal from the gearbox

obd2 gets it`s signal from the abs rings on the front hub

I think that's what he meant, he certainly knows that's the case because he fitted V70 clocks to a obd1 car and they didn't work.. Epic fail Gav lol

So how can I get round this?
How easy will it be to set up an obd1 set up?

Bump.

I use one of these, I don't know if you could tap into the signal from it.

just wire the speedo directly to one of the ABS sensors, if your removing the ABS you can bin 3 of the sensors

[cherry1809]

ABS has already gone. So any sensor will run the speedo? Sounds easy so I expect it isn't. Lol.

yep

Yup, mine is piggybacked off the N/S ABS sensor, because I don't have a speed pick up in my gearbox now.

Doesn't seem to matter which colour wires you connect to the senor wiring either.
