Nest thermostat compatibility with Trane Heat pump

I have a Trane heat pump system.   When I use the Nest install app, it says my system may be incompatible.   See wiring below.  Can anyone tell me how to wire to the Nest 3rd Gen Thermostat?

You have a heat pump system so use the outer labels.

White - W1 to W2/AUX

Blue - B to C

Green - G to G

Yellow - Y yo Y1

Orange - O to OB

Red - R to Rc (jumper to RC not needed)

Thanks !  I’ll give it a try and let you know. 

It worked !  A/C running fine.  Nest app wouldn’t let me test heating because it’s over 90 degrees outside.  Thanks for your help.
