MX Rebreather - BOV OC 2nd stage feed - Connected to the Left post
We connect the Bailout Valve or BOV to the left post to stay consistent with standard UTD/DIR philosophy. UTD philosophy centers around the idea of putting the buddy on the long hose during an OOG, which is connected to the primary post and will not roll off in a restriction. The necklace/backup or in this case BOV, is connected to the left post, which can roll off in a restriction. This is of course not as big an issue as if you rolled off your team mate because if you roll off yourself you can simply reach back and roll it back on.
