Both Molex ?

[foster grant]

ok so i got myself a Cold Cathode set for my pc.....but on it are two Molex , do I use both or just one ?

 

[PhillyDee]

Just one. Thats a passthough connector.

 

[foster grant]

right, so either one yes ?

 

[PhillyDee]

Only one will fit . . . . Its so you can plug it in behind a drive and still power the drive, or a fan, more cathodes etc.

Use the one in the left of the picture.
As Phil said, the other is used as a ‘pass through’ connector
