I have an American Standard c800796p01 board in my Trane XR 14 system ( replaced in 2016 ) . It does not have your typical terminals, everything is spliced in down the line. I am struggling to sort out where my C wire would get spliced in at. Any thoughts would be much apprecaited. Here is an image of the board.
The dip switches (Im sure they dont matter in this case) are setup as follows
To add to this fun situation, my current Thermostat is labeled pretty funky. Here is the pin out
Red - RC jumped to R
Blue - O/B | W1
White - W2 | Aux | E
Green - G
Yellow - Y1
Any thoughts on how to get this set up properly?
