[Healeys] More wire

[I Erbs]

On my back, under the dash. I found a bulb with a single light green wire.
I can see that I need to jumper in a red/white wire/ bulb for my fuel gauge
and that there is no bulb in the oil pressure temp gauge ( how does that
light up,?)
No two wire bulb unaccounted for. The wire harness matches the. Bently
schematic page 298. Any ideas?
