Ok my 08 ss cluster came in today, along with the pillar. I want to use the stock gauge for the vacuum. (Wire colors are from top to bottom in first picture) Black with a white stripe, pink, tannish color, and green. What is each wire for and how can I wire up this gauge to work on an ls model. I decided not to get the voltmeter if I can get this gauge to work. I would really like to use it for the vacuum. Also how do I get the stock pillar in the car out without messing up the airbag? Any help will really be appreciated.
