Brian and Marc,

I installed the DC contamination sensors, O2 and H2O.  I used the 'master' and 'logic in' cables from the 'solenoid power distribution box' off of the third deck.  

R1/R1 is the 'master':  H2O uses red, black, and green.  Blue wire from the sensor is now black.
                        O2 uses brown and blue.  

R3 is 'logic in': wired same as R1/R2.

In addition, I wired up 2 magnahelics using the cable previously used for the magnahelics on the solenoid panel.  R2 is now on R1/R2 exhaust manifold; R3 is on the R3 exhaust manifold.  

When you get some time, please connect the gas shed ends.  I don't know where they go.

Thanks,
Morgan
