Hey sorry to hi-jack thread but is kinda related.
Is there a right and wrong way to connect power to a gauge for the backlight?
For example, my old gauge had a couple of wires linked up, but were not labelled. Being the fool I am I took off the gauge then put the other one in, but thought "hang on, if I get the wires the wrong way round would I blow the bulb in my new gauge?"
So does it matter about the polarity of the wires when connecting up?
Ah crap, that sucks then.
How the fook am I gonna figure out which way round it goes. I could put a multimeter on the wires from the car, but not sure how to check which wires on the actual gauge
