They do "look" identical. But one feels different (factory stitched leather, I installed one too )
Expect the spline index to be different and the stering wheel no longer will be perfectly centered. The old trick of equally and in the same direction tweaking the tie rods to correct this is _extremely_ difficult. You can try but expect a needed alignment. :/
And about 2 minutes with the battery disconnected (and should remain so throughout the proceedure) is sufficient. And don't forget to sync the cable reel too :!:
The installation went very well. Working slowly, it took less than an hour - including the 15 minutes I waited to begin once disconnecting the battery.
Here's how it went: Once the battery was disconnected (the one in the engine compartment - not the IMA), I let it sit for 15 minutes. I then pried the two housing covers off each side of the wheel and took a torx T-30 socket to undo the two sides of the hub/airbag housing underneath (the hub/airbag then practically drops in your lap). The airbag and horn connectors disconnects easily (if you're heavily pulling & prying you're not doing it right, the airbag electrical connector disconnects fairly easily with with a subtle technique which you can learn by trial & error in a few minutes - no I cannot explain it better). The nut is then removed (with a 14mm socket), then you put the new wheel in and button it all up. Easy.
My original foam steering wheel was getting kind of nasty (as has happened to some of you as well) and, for only $6.00 (plus $12.00 shipping) and less than an hours effort, it was a great value for a very nice improvement.
