I've searched for about an hour for a how-to on this but no luck. Picked up an S6 dash today at the pick-part hoping I can make this work in my 2.8 V6.
I must be using the wrong search term or something because there's no way I am the first person to think about this. These white background gauges are awesome. I also snagged the S6 three spoke wheel and plan to go back and grab the rims too.
