There is only one wire you need... the one coming from the clutch itself. The other plug is for a pressure switch, which is unneccesary (redundant) in a 240SX.

Thank you sir, so if i give it a 12 volt source it should click on? Im assuming it the plug closest to the radiator?

thanks

Yes, connect it to your original A/C clutch plug (which is routed through the A/C clutch relay).
