Where is located the speed sensor in the 340?

Thanks

left front wheel on left-hand-drive models...
the cable is driven by the grease-cap of the front wheel bearing.
Which, I might add.. is a totally crap system..like so many other small things are on a 300 series volvo. I've had to rework that thing about 3 times already, and it still functions unreliably.

Thanks for the information
