trouble with toggle switches

[mpeteking]

Hi all

i am trying to wire a led toggle switch to the cathodes inside my pc but i cant get it to work. it works when i only use the power and acc pin and i don't put the ground in but the led does not work.

when i do put the ground wire on, i split the cathode ground wire and solder the ground to the toggle but it shorts my computer and shuts it down

Please can anyone help?

Cheers

sorry, ok i am using the cathode inverter http://www.overclockers.co.uk/showproduct.php?prodid=CM-003-RV&groupid=701&catid=1428&subcat=1430that comes with the pack as standard and i have chopped the red and yellow wire and put the red wire on the power on the toggle and the yellow on the acc.

when i splice the black wire so i can ground the switch to make the led work it switches my computer off?

i just cant get my head around it?
