After making it through last summer without A/C, I decided this winter I would look into my system come spring.

I bought this manifold set http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=92649 from Harbor Frieght.

My car has a sticker on it saying it was converted to R134a in 2001.

I just went and tried to hook the gauges up and the connections would not fit.... I attached a pic of the RED High Side connector from my car so that hopefully someone could tell me if this truly is a R134a connection or if it is still the old R12 connection.

My question...why won't my gauges fit onto the connection? Do I need to buy some sort of converter?

Thanks! I'm sure I'll have tons more questions once I get the darn thing hooked up!
