That is the one I used works a treat
EDIT:
My set up for this question will be as your looking at the car Fan 1 is the Passenger side, Fan 2 is the Driver side
1. Cut the ends of both wire leads long and short, that connect directly to the stock fans.
2. Strip off the black heat jacket.
3. Take Blue wires from each harness and solder them to the Blue wire on fan 2.
4. Take Yellow wires from each harness and solder them to the Black wire on fan 2.
5. Take Green wires from each harness and solder them to the Blue wire on fan 1.
6. Take Black wires from each harness and solder them to the Black wire on fan 1.
7. Heat shrink all connections and then slide some sort of loom over them for protection.
8. Connect everything up and that should be that?
