Hi,

On my new acewell there is an option to have ab oil pressure warnig light with one wire.

On my loom the oil pressure light I have on my loom I have 2 wires connecting to the oil light. - I am assuming one is just an earth? and one is the 12v feed.
So would I be right is assuming that I can connect the 12v fed to the light on the acewell and isolate the other wire as its only an earth.

Does this make sense or am I missing something?

Thanks

Frank

The oil pressure switch is what does the grounding, so the lamp will need an ignition switched +ve supply on one side, and be grounded via the pressure switch on the other.
