Relays

I just bought a 99 F250 Superduty with a diesel. On top of the engine there are 2 relays. A short one and a tall one. I'm pretty sure the small one is the glow plug relay. Can anyone tell me what the tall one is for. The glow plug relay is bad and want to make sure i replace the correct one. Thanks a bunch Lance
