I don't have the exact info for the temperature gauge, but what I normally do in such case is switch to a complete other eeprom with the correct desired setting (Celcius in this case).
Transfer the crypted immo area from 12A0-14FF and you can also copy/set some other settings if you like.
Write that new eeprom and you should be set

Thanks for the reply! I actually think my needle is in the wrong place.
Anyway, the problem I have now is the "bulb error" light. I had a thought recently that the position of symbols might be different between Japanese and US RPM gauge and I was right. The Speedo has different symbols but with the same meaning, not too bothered about that. So, when the handbrake is on the bulb error comes on because on the US cluster it is "PARK".
As you can see here:
US speedo (installed), JPN speedo.
JPN RPM (installed), US RPM.
Would doing your method fix this? I guess so, right. I'm using the clip, not soldering. Can it really cause damage?
