Tamora rogue wire?

[Ando74]

Anyone know if the other end of the black wire with blue connectors should be attached anywhere? Looks like some kind of grounding wire, one end attached to engine block but the other is just loose.... Not noticed any problems, just noticed the loose wire while poking around nearby..... It may have always been like that!

Cars been up on stands having a bit of TLC over the winter, thought I'd check before 1st long run out. Cheers.

Alternative earth for the oil pressure sender?

I think you're right cheers. That's certainly where it points to but there's nowhere to attach it now. Possibly leftover from a previous sender/fix. Can see easier now the bonnet is off...
