Gauge cluster pins that needed to light gauges (gauges installed in bar)

[truegearhead]

Ok, heres an odd ball question that should challenge you guys. I'm working on a pub shed in my back yard and have some old gauges in the bar that I'd like to light up. The bar lights run on 12V so I have the power. Anyone know what pins (power and ground) I would need to connect?

The blue+gray wire coming out of the gauge through the blue connector is connected to the same 12V rail as the gauge backlights. You could try powering that blue+gray wire with 12V and see if it turns the bulbs on. Be careful because now you are applying power in the wrong direction since the gauge cluster powers that blue+gray wire to apply backlight to the centre console (radio, climate control, buttons, etc).
