The Budaschnozzle has two wires for the heating element - they'll be the thick ones - and two for the thermistor - they'll be the thinner ones. There is no polarity on either, but follow the colour guide if they're in red/black pairs.
How they are connected to your electronics board depends entirely on which board you have. Either post it here or google for " wiring diagram" - e.g. for the RAMPS board: [
