Thanks for the posts. So it seems I'm look for either a White wire with grey stripe or Grey with white stripe. Can't find either and I have wires on instrument connector as per Electrical Diagram on mine.
The only White Grey wire I can find on the vehicle goes to the throttle pedal connector.
So it looks like I'll have to run a wire from pin 19 of ECM.
The rev counter is an LR part, YAE100790, available from any LR parts place. Should be able to source it at ~£85 inc VAT, if not these were the cheapest guys online..
TD5 Rev Counter or for £20 more you can buy it from Croytec with some cable ties and wires :roll: :roll:
I went for LR TD5 counter as it's pre-calibrated for taking speed feed from ECM and has lower range 0-5000. There are cheaper VDO ones available.
Cheers
