It depends on if the connecting rods use a full-floating or a semi-floating design. If it is a full-floating design, the piston should have spiral clips that snap into the side of the piston where the wrist pin slides trough to hold it in. Position the rod and piston, and slide the wrist pin through. Then install the clips. If your vehicle has the semi-floating design, the wrist pin is pressed into the connecting rod. This will require a shop press and the proper adapters to press the wrist pin into the connecting rod.
