Pm'd one of the guys on here to locate OBDII connector - just below bonnet release catch in driver's footwell.
Had to remove the central console section - don't panic - just lifts out - gently pull upwards where ashtray removed from - unscrew gearknob and it slides over gearstick - you can leave wires connected - cig lighter etc.
This gives you access to rear 'pocket' of console and wire can be fished from footwell through an aperture in rear on console.
Took me about an hour - had a bit of fun fishing the cable but could be done in about 30 minutes now.
Have attached a few pics.
Note - If you remove the Scangauge from the car - when you reconnect it make sure the car is running or the ABS light starts to flash.
Central console section lifted out.
View of rear of pocket to console showing aperture - right hand side for Scangauge cable.
Scangauge installed.
