The wires will go to Rh and W1
But you need a extra wire for C common to give the Nest 24v AC power.
Can you pull a new Thermostat wire up the wall from the system with 5 colored wires is it visible where the old wire comes from?
And the heating system needs a C terminal on the furnace to connect the (normally use blue) wire to C.
Follow the wire back to the system and take a pic of where they connect to the heating system so we can determine if you have a way to connect a C wire.
yea I finally got it to work. I installed the c wire to the system and somehow the nest thermostat keep sayin that there no power on the c wire. so I bought a 24 volt transformer and yes! worked perfect. but thanks for asking I appreciated.
