There's a small connector onto the negative battery terminal. How do I disconnect it and where do the wires go? I assume I need to unclip it by pushing down the centre prong which should lift the hidden hook. It didn't work. Was I doing it wrong? Job done for now but it might be easier in the future if I could remove it.

It’s for the battery monitor. Like my Clio it has Stop/Start.

You just push down the top ’tang’ and gently pull the connector plug out. Don’t pull it by the wires though.

Thanks. I was doing it right. Next time I need to do it I'll have the confidence to try a little harder!

Often with them, you need to push in the whole connector to release tension on the tab...then it releases more easily.

Just out of curiosity anyone know what's inside the mysterious black block next to the connector? (a very low value resistor perhaps?)
Why do you need to remove the connector at all?
....late edit I just read this, so perhaps you do need to disconnect it although I don't understand why that might be.
Does it prevent access to the clamp nut? (It's hard to see from the photo what the clearance is for a spanner or socket)

As far as I know it’s a resistor So the BMS can monitor the voltage drop across it.
