I've just bought a set of omori electrical gauges (oil temp, oil pressure and water temp).
They came with the appropriate sensors but the wires have been cut 3inches from each end.

Wire colours from the gauges are white - red - black - yellow - orange on the temp gauges and the oil pressure gauge also has blue - grey - brown - black along with the previous colours.

Any help with this would be much appreciated, I've looked all over the net trying to find wiring or install instructions with no success. I can't even find an omori website.

 

Managed to figure out some of the wires using a power probe

red = 12v power
black = earth
white = gauge backlight (12v ig?)
orange and yellow = sensor
sensor = earthed to engine

Those wires work for the temp gauges but still unsure about the oil pressure sensor wiring which has the extra brown black and grey wires....
