[* red] This position on the logic board has three closely-spaced connectors for the power button, ambient temp sensor, and the CPU fan. Unplug them.
[* orange] Disconnect these three connectors for the HD temp sensor, optical drive temp sensor, and hard drive fan.
+ [* black] Each one of these three connectors has a different number of pins so you can't mix them up when reconnecting. Thanks, Apple!
