You can get a recharge kit with a gauge at most part stores. The connector will only fit on the low pressure port which is the one you want.

For charging use low pressure port what is on thick piping what is where you described.
High pressure port (small pipes) on ML from what I remember is on front of condenser behind front grille.

If it is connected to a plastic block that goes under the metal strap it is just a plastic line to keep the block from getting lost.
