Rb25det Oil Pressure Switch Info Needed

[midnight]

hi im doing a conversion in my s13 to rb25, almost finished with the wiring, just wondering about the rb25 oil pressure switch

it has 2 pins, am I right in assuming one for oil pressure light and one for a gauge?

and if so which is which? on the sr loom im splicing to theres only 1 pin, for the oil pressure light.

thanks

check with multi meter the pin for the light will be earthed when engine is off and will open circuit when you have oil pressure otherwise get your old switch from original engine it should bolt into the rb block if you dont have it then get one for a r31 rb30 from repco ect just tell them you want one for light only no gauge.
