1. Make sure you have eye sight a surgeon would be jealous of, you will need it. It's difficult to believe how small those screws are till you get them out.

2. Buy the suction pliers. I tried the one suction cup and by God's grace didn't rip the cable right out. It was MUCH tighter than I imagined. I was being super careful and still it popped off with tremendous force. The clip flew off and amazingly the cable didn't snap.

3. Bright light, magnetic pad for the screws and lots of care you can do it.
