             The correct PC3 for the MT-03 is a 422-411 according to Dynojet.
             
            
 The correct one for the X/R is 412-411 (which will fit/work on the Z). There wasn't ever officially a PC3 for the Z as the Tenere came out in 2008 when the PCV had just been introduced and that is what Dynojet recommended - there was no need for them to produce a PC3 specifically for the Tenere. OTR advertised/sold a PC3 for the Tenere for a few years but that was always the 412-411 X/R version with a different sticker on the box.
             
            
 The 412-410 PC3 is for the Raptor 700. Several people have successfully used this one on the XT660, although AFAIK the length of some of the wiring to/from the various piggyback connectors is slightly different and may need careful routing.
