The oil pressure switch is earthed locally through its body, as such is wired with just a single conductor.

The plug had two terminals in use or I thought were in use could I have got this wrong
Wire colour was black at connector but I found a cream wire just hanging there

what vehicle is it in

Discovery 2 td5 2001

Oh ok i only have info for Defender sorry

Ok Thanks
Started the engine today and red oil warning light on.

found you this for disco 2

Oil pressure warning lamp The oil pressure warning lamp is connected to the instrument pack from pin C0230-6 on a WN wire to the oil pressure warning switch, the oil pressure warning switch is locally earthed. DESCRIPTION AND OPERATION DISCOVERY 4.175 If the oil pressure switch closes, an earth circuit via the closed switch contacts is completed and the oil pressure warning lamp will be illuminated. Power for the warning lamp is internally connected to a power supply from pin C0230-19. Pin C0239-19 is supplied power from the ignition feed from fuse 27 in the passenger compartment fusebox.

hi gents found this pic on a previous post this is my connector .
it has two wires
does the black one just go to a generic earth ?

On a Defender it earths through the body of the sensor I think.....

Thanks Dave seems strange the disco is different

Think I will just run the black to earth and see what happens

The black wire is just for aspect cos the switch is earthed via fixing, the WN wire is impotant and has to go to C0612 - 1, if the lamp is always on then the switch is stuck closed, you dont have oil pressure or if the WN wire is broken it touches earth somewhere

I made up a temporary connector but have installed it on the bottom terminal of the sensor so that is why the warning is on

yes, that terminal is earthed so you have to connect the WN wire to the other terminal, the switch is normally closed to earth so the warning is on untill the oil pressure opens it

tomorrow we start again
(not mentioning i put the clutch plate in the wrong way round)
