It's not really a relay question, it's an Ohm's law question. It will draw 6V/68Ohm =~ 90 mA. If your 6V power supply can handle that load, you're all set. If it can't, don't run a resistor in series, as that will drop voltage, and the resistor won't see the 6V it needs. If your 6V power supply can't supply sufficient current, you'll need a different relay or a beefier power supply. Alternately, you can use a solid state relay, the heart of which is a MOSFET. These might have a slightly higher resistance in the switched channel (like a 0.1 Ohm or something like that) but have the advantages of greater reliability due to no moving parts and consumption of negligible power on the "coil."Relays look cooler, though. Kind of retro 50s.
It's unclear from yur posting whether "working on" means building or repairing. Since you're wondering about how to wire the relay, I'm guessing that you're building.
Hope this helps.
