The restoration of my late 1973 (build) Plus 8 is continuing very slowly, but is progressing. I am now dealing with the wiring - every connector is corroded and none of the earths are good. As part of tracing of the wires, I have two lamps on the dash and I do not know what they are for. Could someone with a similar Pus 8 please tell me? Also, though I have an oil pressure switch on the oil pump housing, there does not seem to be a wire in the old harness for it and there is no mention of such a switch or warning lamp on the appropriate GoMoG wiring diagram. Was the switch wired in and back to the dash? If so, what colour is/was the wire?

I prepared an annotated pic of the dash showing the lights in question but I cannot understand the help section on how to attach / post the pic. So words will have to do:

In the speedo, there is at the bottom left a blue high beam warning light, and bottom right the ignition light. Centrally, between the speedo and the instrument cluster is a horizontal row of three lights; on the right is the indicator warning light, but what please are the other two - a larger red central light and a smaller red light on the left.?

Any and all help greatly appreciated.
