Ah - this is driving me mad - two days with wiring diagrams and spaghetti cables - the jap colour codes are completely different... 
Found out how to do smilly, jumpy things though 
Not able to trace down the difference in the wiring - and concerned to do the light thing, just in case I send a voltage down the wrong end of the ecu.....After a lot of head scratching and a garage that looks like a tdm has exploded in it ....Maybe I have given the garage to much credit... maybe they haven't changed the speedo .... maybe they just change the mechanical bits and have left the electronics inside..... so I in typical open heart surgery - I opened the speedo unit.On the side of the speedo - is some electrics - with two black plastic posts - I assume and they look like the starts of a reed switch, but nothing runs between them or looks like it would at any speed - I assume the "new" mechanics is missing the plate, which does the thing at 180 kph .... cables state ground, ignition, output a and output b....So the plan - unless the people from the forum (those down under may know lots) can give me any other ideas - assemble it all back together - see what the voltage is between ground and output a and output b - and in true blue peter style - some silver foil in between the black posts and see what happens ...Have done a major google thing but with no joy, no red max, no tdm unrestrict - Number 5 - do you have any posts/sites ???Thanks for all the comments - I'd put up with 180 kph is the performance was there...Cheers Mr Devil
