Product review (5 stars): IM4 Ice Maker install
We bought a GE Artistry series refrigerator sans ice maker.  Found the IM4 on Amazon for a good price of $74.  The install wasn't without problems and required a call to GE product support for clarification.  The IM4 fits many models of GE refrigerators and the instructions with the IM4 specify installing according to section S (or other letter) in the install manual. A sticker on the back of the fridge (tiny printing) also tells which lettered section to use for the correct instructions.  The actual refrigerator specified 'T' specs which are not in the IM4 manual.  The T specs are in the IM6 manual which I got on line from the GE rep.  No problems after that although I would have thought the lower rear cardboard cover on the fridge would have been pre-stamped with a knock-out for the water valve.  When fitting an ice maker to an Artistry refrigerator, I'd choose the IM6 upgrade, but the IM4 works just fine.
