First thing to do with either set is check that you have the right voltages at the sensors.
Disconnect the low pressure switch on the side of the head, turn on the ignition, you should have 12v there. If you ground this then the oil pressure light should come on.
The secondary sensor is on the oil filter housing, this should sound the buzzer and light the light if the engine is running at over 1800rpm and the pressure drops below 2.0bar. There is a circuit on the back of the clocks that takes a pulse from the tci to tell if the engine is running at sufficient rpm then uses the secondary oil pressure switch. Mark1_gls and rubjonny have been helping work through it with me. I found this link useful :

It's a bit of a pain to get to, as you have to take most of the clocks apart. You should be able to take the circuit out of one of the other sets of clocks and transfer it into the one you want to keep, and that will probably fix the issues you're having.

I haven't stripped mine yet but looking at the photo it's looks like a few resistors and caps, a few diodes, a relay and what looks like a simple logic chip.

So I have this set of clocks from ebay with the fancy mpg calculator vacuum thing on the back. Taking it apart to try and resolve the headlight main beam light not working and the buzzer oil light issue when i notice this socket (white arrow) whats it for? What plugs in there?

its just a normal 12v bulb with a blue or amber cover depending on the age of the clocks

The trouble with doing nothing is that you never know when you are finished.
