Manda, You will need to obtain a wiring diagram and connector view diagram. The red and black wires should be the heater wires and the green and tan wires are your feedback wires. Your wiring diagram will label the four wires with a 1,2,3 and 4. The connector view will give you the corresponding location for each wire. Very simple once you have the diagrams. Good luck.
