great info, thanks

sounds like I'd need a bit of loom, a wiring diagram and some patience if I want to go down this route

Phase 1's upto around late 1995 ish are full mechanical speedo (ie cable driven)

Late Phase 1's (late 1995-1996 ish) are semi-electric speedo (ie electrically driven but with mechanical odometer)

Phase 2 and 3 (1996 onwards) are full electric speedo (ie electrically driven and with a digitial odometer)

I know that the wiring is very different between Phase 1 and Phase 2/3 but not sure on precise details - Phase 1 is similar style wiring/connectors to a ZX (but almost certainly not pin compatible) with slot style plugs around the outside of the back of the clocks, whereas Phase 2/3 use a couple of high density plugs from what I recall.
