Newbie thermostat wiring question

I disconnected my four-wire thermostat and forgot how it was wired. This is for a gas boiler - there's no cooling involved. A picture of my best guess is below - which didn't work. Any idea what's wrong?

What are the wires connected to at the other end of the cable where it connects to the boiler?

I always tell myself... " I'll remember " ... and I never do... so at some point we have to listen to that voice in your head that is whispering ... "NO YOU WON'T! WRITE IT DOWN OR TAKE A PICTURE!"
