Hooking up Nest to Trane XL1400 (Help Please)

I was wondering if someone could tell me the correct wiring hookup for the Nest Thermostat please, there are no wires hooked up on the left side! Thank You

I would advise heavy against the use of the Nest. They are arguably the worst choice one can make for a thermostat. They have created many service calls for me.
What kind of system are you trying to control?

It's a single unit Trane XL1400 with electric cooling and gas heating!

Welcome to the forums.

It's not just the nest that has issues. It's many of the power stealing thermostats.
I've never had any problems with nests I've installed other than the occasional defective base.
They do seem to have user operational issues.

R -------> Red --------> Rh
W1 --- -> White ------> W1
Y ------> Yellow -------> Y1
G ----- -> Green ------> G
B ----- -> Blue ---------> C

Honeywell makes several wifi stats as well a sEcobee.

Nevermind, they had the blue wire hooked up on the old thermostat, but it wasn't even wired up on the ac unit!
