Help Please With Oil Pressure Gauge Wiring

Morning all.
Have got hold of a oil pressure gauge via Ebay but no wiring instructions and very different from my current one.
The gauge has the usual power & earth but has two other terminals marked B & T-any ideas?
Also, the sender that attaches to the block has two connection points I assume for connection to the gauge and the original car wiring for oil pressure light.
One is indicated G and the other WK-any idea's which is which?
Thanks

One of the gauge wires is probably for backlighting, but which one I don't know.

Assuming the sender is a VDO one, then :
G - sensor pressure output
WK - low pressure warning light

G = ground so generally black wire to that and red wire to the other one. You'll probably have to get an adaptor so you can still use your pressure switch.
