You simply remove the calibrated outer plate pair and connect both remaining inner links with the KMC Missing Link. As I've already stated, I don't feel comfortable running the KMC missing link on a Campy chain because you simply don't know if KMC is making them precisely enough for the Campy chain tolerances. At least if you go with a KMC 11-speed chain + Missing Link you know the same company made both, which means there's a better chance that the chain and missing link are within the same range of acceptable tolerances.
