Ashley 4840 exhaust sensor location

[mooseracing]

I grabbed a unused closeout a while back that I haven't had time to mess with. It hasn't been burnt it but it was missing one of the RTD sensors. The one is right above the heat exchanger, can anyone point me to where the second should be placed? It doesn't have one installed currently but the board will error out if the second isn't plugged in .


The manual list two sensors but the diagram doesn't show both, unless I'm missing it.


Thanks
