Check fuse 2

Check fuse 19

you've already checked/swapped the relay



The wire colours are labelled on the diagram, however easy way to check.....


Remove centre pod

get the plug with the 5 wires

with a multimeter set to volts, put one probe on the RED wire (pin 1), and the other probe on the BROWN wire (pin 2)

switch on ign to pos II or start the car, doesn't matter.

you should have 12v or 14v depending on what you did.

This will check if you have power to the gauge.
