Where is the starter relay located? on 2003 Volkswagen GTI

Vehicle won't start but the battery is good. Will start when you pop the clutch. Someone said to try the starter relay, but can't find it. Thanks.

There should also be a neutral(clutch) safety switch underneath at the clutch pedal so you can't crank it if you don't have your foot down on the clutch.TEST don't guess before replacing!
