i'll have a pic soon but heres how u do it:
take a positive wire from the PSU and run it to the switch, then run a wire from the switch to the fan. it should connect to the fans positive. IMPORTANT! it should go from the fan to the ground wire in 1 of your molex connectors, or it should touch your case. IE: DO NOT CONNECT it to your PSU negative wire, IT WILL SHORT out. i hope this helps
