The middle one. You have RB20, right? There should be three wires: two white ones and a clear one. The clear on is the one you want. It should go into the shielded portion of the cable. The other two are heater wires.

MAKE SURE YOU SEPARATE THE SHIELDING FROM THE WIRE BECAUSE THAT WILL GIVE A FALSE READ.
