As we all know, the Ouroboros O2 sensor bay accomodates a fourth O2 sensor and (in my unit) even has the pin to plug into this auxilliary sensor. The debate about the usefullness of this option notwithstanding, I do want to implement it. So my questions is: does anybody know where the cable for this fourth cell output terminates? And if so, is there a way to extricate it and configure to connect to a VR3? This would afford an independent real-time PO2 read-out for an additional level of redundancy.
Again I do not wish to debate the efficacy of this option (I am willing to concede that this is a case of 'overkill' and paranoia), but, be that as it may, I would greatly appreciate any suggestions as to how this modification could best be accomplished.
