For the JX engine you need the following switches:

Oil pressure switch, 0.9 bar, unipolar, grey
Part-Nr: 068919081C (actually we've changed the number in 068919081A)

Oil pressure switch, 1.4 bar, unipolar, black
Part-Nr: 068919081

Thanks. Which one goes where

[gotjosh]

they are color coded... as best as i can figure, the grey one goes where the old grey one was which is on the head of the oil filter
the black one goes behind the engine.

Thanks for that, Do you know which one activates the buzzer and/or oil light, and for that matter why have two?

low pressure switch is start up to say you have oil pressure, but if that ever goes off while engine running then crank is probably toast already, high pressure is for BOD circuit and says at 2000rpm you have decent acceptable oil pressure, ie real world, system works fine, problems are usually because people bypass the system to cover up the low oil pressure then flog the van and new owner has to find the fault

Hey gotjosh,

When you say "behind the engine" you mean the head under the black electric box? I am trying to find out where...

My problem is this:
