Activity light

[Alain]

Hi,

I own a G4 and I bought a Firewire enclosure for 4 drives.
I'm ready to install 4 IDE IBM DeskStar drives.

I would like to "see" the activity of each drive.
The enclosure has 4 diods (with nude cables) the allow it.

Where do I connect this cables on each drive ?
I'm unable to find a diagram on the net.
The drives have (to my point of vue) no extra connector.

Any help will be appreciated.
TIA

Alain
