Vacuum component

Morning all.

Can some one help me identify this, it’s off a T piece on my rear diff lock, I’ve checked the vacuum diagrams and it Dosent seem to correspond to anything on the diagram?

Any help appreciated.

should be connected to the front difflock, it's a vacuum electrical switch that works when you select front difflock to signal the small foam covered circuit board that is wired into the loom so the front difflock light flashes to say 'did you mean to engage front difflock ?' before the difflock enagages and light goes solid and you loose steering sensitivity - it's a safety device in case you pull the wrong switch or child messes with it

Cheers aidan .

Very informative, odd that I can’t find it from any of the drawings very good to know though.

The vehicle came from factory with a front And rear diff lock so it’s more then likely for that.
But on the face of it I thought it was single looking at it, but the m codes and the parts behind the dash say otherwise.
