Once you have the front casing off, 6 tabs for soldering the chip are exposed (Photo 1). You have to short the black and green cables to fool the camera that there is a lens installed (Photo 2). Hide the AF confirm chip somewhere under the bottom metal panel (Photo 3). Use adhesive tape/ribbon to cover your job cleanly and nicely. More information is on the photos as notes.

I may be wrong on the pin-out below, so please test it with a multimeter.

Put your camera back together, put the battery in and see if the tiny chip is reporting a lens. In my case it reports a 50mm f/2.0 lens. This varies to what you have on the chip. You can ask the seller of the chip to program a specific number for you, too.
