The O2 Optimizer (little black box with 2x leads/connectors) should just plug straight between the bike's O2 sensor male and female connectors (on post 2007 bikes). Never heard of anyone having different connectors? 2006 and earlier didn't have an O2 sensor at all, so don't need the O2 optimizer.

The PCV plugs into the TPS, injector, crank position sensor and has an earth lead. The PCV itself does not have a connection to the O2 sensor at all.

The Kev mod should be removed as the PCV does the same job. You will need to reconnect the wire which was cut to originally install the mod.

PS - I've moved this to the tech section. Newbies Reception Lounge is really just for hellos, initial introductions and other such social pleasantries!
