This part is potentially dangerous. I removed the right side flex cable by putting my pry tool alogn the end length of the cable -pushing up close to the base of the connector. I think the connector is held on by adhesive to the yellow film between the connectors.

I don't understand this connector that well. After that you can fold over the board towards the left. I might not have done this the proper way. You've been warned.

For reassembly I lowered the logic board onto the plate with the connector.
