Don't waste your money on this gauge.  I purchased it through Amazon and had it professionally installed when my car was tuned.  Gauge worked one day then quit.  It only shows the default 14.7 AF reading at all times.  My installer called Autometer and trouble shot the gauge.  They keep saying that it's a ground even though he grounded it exactly as they instructed and it still doesn't work.  Check the internet before buying.  Tons of others having the same issues with this gauge.  Unfortunately, the return period to Amazon expired last week due to delays getting this installed.  I'm left to deal with Autometer customer service who thus far, have not been any help.  Do yourself a favor and spend your $300 on a quality gauge and don't waste it on this model.
