The gauge should be the same between a 08 and 09 should it not?

 

It seems that way from the 09 pics.

 

Do you have a part number, and how was the installation

 

As stated, just get it in electrical: http://www.summitracing.com/parts/ATM-6159

 

Or for $50 more go with the Aeroforce. and it reads every single sensor and then some on the Vehicle....This plugs right into your OBD port
