I just bought a used G5 and was installing a blue tooth module and noticed a loose wire inside in the area where the bluetooth module mounts. It has a small black plastic end on it. Some one told me it was a heat sensor and not to worry about it. Can anyone tell me where this wire is suppose to go or does it just stick up in free space? I'll post a pick. Notice it just below the wires and bluetooth module. Thanks for any help. Robert
