Basically I'm trying to wire in a speco (Norby's I believe) gauge. its a digital one.

The gauge is an oil temp, And i'm tring to wire it directly into the blackout cluster wire loom.
so it has two wires from the gauge a blue and white not sure which is which but 50% chance lol but what colour wires are the ones for the oil temp in the blackout cluster

Cheers Guys
