I installed the water torture mod. Took a few pictures to help. One confusing thing was instructions said red wire, but both wires on the mod were black. If you followed the black wire, you could see underneath it was red. I took a few pictures of where the 9 pin molex is. After connecting up, and turned game on, the blue light for the mod stays on. However, during the water torture mode, it starts to blink several times during the mode. Pretty cool!
Heres a link to pictures I took including a short video of the water torture mod "blinking" when the mode is in play:
