Isn’t it next to the oil filter? 1 or 2 wires coming out of it.

Thank you so much  m8

I knew the little bleeder was hiding somewhere Lol..............I might of guessed they would put in the most awkward place.

Yes I have an older Calibra turbo 1992 K reg..........so the switch in the first pic is my one..........the second one shown is for 1993 onwards.

Hi age 

Just an update on my Oil pressure problem..............I located the switch and connected my oil pressure gauge......and the test proved that the

pressure at idle.......through to engine at 3,000 rpm were spot on with no needle shake. So the switch could be the gremlin.

I placed the car on ramps and got underneath........but hell......what a difficult task.......every thing was in the way......drive shaft metal

pipes.....etc....it was like key hole surgery Lol...........then trying to insert a gauge adapter.....then the gauge tester hose was like wrestling a 

Python Snake.  But needed to be done regardless.

Many thanks once again

The pictures were great.....Well done.
