Anyone know the size of the nut that is one the negative battery terminal of the 2021 (and likely older) models? Not the terminal clamp nut but rather the other one on the shunt. I tried a M8 and it seems a bit too small. I think an M10 is too big so it is probably an imperial size?

That is probably incorrect use of terminology by me. By shunt I mean the metal bit connected to the battery terminal like so

Thanks, I'll have a look at 3/8. I have to touch is since the bolt is missing!

Very unlikely to be imperial size, most likely metric 9mm. Remember it's Japanese so metric is the go!

more likely to be 9mm on a Toyota is there any codes you need to know when you disconnect ?
I only say that as I have some older Toyota radios that work fine if i knew the pin code.
