Green wire Is for sure a temp sensor wire, but I think that relay may be for a TCS, anybody else have one there, I think maybe somebody removed the TCS and left the wires for it. Would that explain why I have a two temp sensors or do they always have one in the t-stat housing and head like mine?
small green wire with white stripe on left was cut off and just hanging there, not sure what that was for yet. Bigger green on right is temp.
