I think they are both operating on 0-5 volts as the relay. I am pretty sure 5 for both means that throttle is wide open and there is no O2. I could be wrong in that the O2 could be 0 for no O2 and 5 for way too lean.
Either way I am prety sure I can connect them to the same switch and have it run in reverse on one and forward on the other(with two dials/rods connected together and just switch the direction of resistance if they are opposite or leave the same if they are the same).
I don't forsee it causing extra knock or pre-ignition, but I could be wrong. Christ, aerohead anyone?
