The directions in the recharge kit I purchased from Autozone is a little vague as to which connnection I need to use to connect my recharge kit to the system. There are two quick connect fittings on the passenger side of the truck. One is directly connected to a metal canister, which I assume is a expansion cansister of some sort. The other fitting is on a hard line next to the radiator expansion tank.

Which fitting do I connect to?

Thanks
