Thread: Speedo Corrector Installation for Series II Disco

I'm wondering if anyone has fitted a speedometer corrector to a Series II Disco (the Silicon Chip project from Dec 2006 - which Jaycar sell as Kit KC5435, for example). If so, what I'm interested in is:
- Where did you mount the unit?
- Where did you pick up the signal from the speed sensor to the speedo?

I'm quite comfortable with the electronics involved here (and I have the RAVE CD for the wiring diagram), but as I've only recently bought the vehicle (2003 TD5) I haven't had any experience taking the dash and instrument binnacle apart yet so any advice you can give me before I commence surgery would be welcome.

The car currently has 265x75x16 tyres so it's speedo is reading 10% low and I'd like to make it correct at 100kph but as I intend to change the tyres to something a little smaller in 6 months or so I want the flexibility to tweak it again to suit whatever I put on. This makes the Silicon Chip project quite attractive.

Thanks in advance.

(I have done a search and checked out all 14 pages of Tutorials without finding anything but feel free to correct me if this has been covered previously.)

Sorry to start this thread up again, would the Truespeed Speedo correction box work on 1994 range rover classic soft dash?
