SOURCE: Wiring a thermostat.
The green one is for the evaporator fan motor relay. The white one is for the heat sequencer. The one coming out of the transformer is usually red BUT it will be the power so attach it to the terminal labeled R on the thermostat. If there is a RH and a RC, put a jumper in between them. See if the purple and brown ones go to the fan motor, if so, then just cap them off with wire nuts, and that should have your heat working. Check to make sure the green and white wires go to their designated areas (the heat sequencer looks like a stacked set of thermal overload switches and the relay looks like, well, a relay) and neither ground out before flipping on power or you will pop your transformer.
