Help needed installing an Iris CT101 thermostat

Trying to change out a Trane touch screen thermostat. My issue is that the Trane wiring is color coded and doesn't match the wiring codes in the Iris installation guide. I have attached photos. Any help would be appreciated.

Welcome to the forums.

Is the bottom picture the old thermostat and do I have the colors and terminals ID'ed correctly ?

Y2 = black
X2 = tan
W1 = white
R = red
O = orange
Y = yellow
G = green
B = blue

OLD - COLOR -NEW
Y2 = black = Y2
X2 = tan = not used
W1 = white = W2
R = red = Rc & Rh (install jumper)
O = orange = O
Y = yellow = Y
G = green = G
B = blue = C

This is what I have as preliminary wiring. Houston, the forum pro, will stop by and confirm.
