Oil Pressure, and Oil temp.

Looking at them, I have two guages, and two "looms" if you can call them that.

Now I've got a funny feeling I'm missing something, as there are 3 screw type things, with nuts on on the rear, and I assume these for the sensors. The sensors being the thing I'm missing.

Can anyone help? See photos below....

You can see the three pins sticking up..



From the guages comes this, a connector block, and a power supply thingy thing.








The loom finishes with two wires as show below








If anyopne knows what I'm missing, can they point me in a direction to find the parts I need?


Thanks

 

The black and red wires are + and - for the lighting of the gauge.
And the 3 on the back are
(G) Ground
(S) Sensor
(I) Ignition

From the look of the Gauge in the pic you have the Auto Gauge Indiglow type

 

you will need two sender units, one to measure oil pressure and one to measure oil temp, these screw into the engine, the pressure one goes instead of the original oil pressure switch, and the oil temp instead of the sump plug. Good luck fitting the pressure sender on a zetec-s engine!!! I fitted one on my old 1.6 focus (same enging as in the ZS), and the pressure gauge sender is a lot bigger than the standard oil pressure switch. This meant it fouled a piece sticking out of the block, so i had 6" of oil hose made up, then mounted it up and out of the way behind the inlet manifold!
