Installed the mod on Monday, love it! Instructions were top notch, easy to follow.
One thing I'd like to point out. Make sure there is plenty of slack in the cable that leads to the head. I had my cable routed through a hook in the back corner, and that didn't leave enough slack for when the head was lowered. I was very careful in lowering the head the first time, and realized there was tension on the mod cable leading to the head, and caught it before there was any serious damage (did bend a couple of molex connector pins slightly, but nothing broken). Just be very careful lowering your head the first time after the mod install, and make sure there is plenty of slack. Removing the cable from the back corner hook gave me the slack I needed to lower the head, without the cable getting in the way.
