Hey guys I know Im needing to recharge my AC system but I'm not sure where to plug up the charging system.. I have an 06 c350 and when I look down on the drivers side under the hood I see two points where I would plug one into the charger..but neither is color coated(it's the blue one that usually gets plugged into) so I don't know which one to use or if I'm even looking at the right place. Sorry if this is confusing.. Basically where do I charge my AC from..? Thanks, Chris

You only need to purchase your 134a from Autozone or Advance Auto. The high and low sides have different size connections. The 134a can won't let you hook to the wrong one. It goes to the low side BTW.
