What about speedometer ?Nothing's impossible, you may be able to bodge the puma temp sensor into the TDi engine, and alter the fuel gauge with resistors. Sounds like a lot of work for a cosmetic look.
Thank you so much Mick, I guess this is what I need.Do a google search, there’s a guy on the Defender2 forum who has developed a proper unit to run all the Puma dash from any (back to 200tdi I think) engine. I can’t think of the guys name.

The puma tachometer, warning lights and coolant gauge are all driven over the CAN bus rather than by analog ECU outputs. So you'd need a standalone ECU to take the inputs from the oil pressure switch, coolant sensor and an engine speed signal from somewhere, and output them as a CAN protocol which the puma gauge cluster understands. Not as simple as putting the tdci sensors on a tdi engine I'm afraid.
