Gen 1 PCM works fine with S197 guages. If you can install an 11-14 guage cluster, you can even retain PATS. If not, there are 2 options: PATS delete on the PCM, OR run the control pack strategy. Either way, you WILL need a custom tune. Especially if passing smog is necessary.
No adapters needed for any accessory. Use the coyote stuff as is, and install an EPAS. I actually ran my hydraulic PS for 2 years. (made my own power steering mounting plate, and got a longer AC belt to run the pump) But, kept blowing out the PS pump at track days. The saginaw 2 pump is known in the corvette group as not high RPM friendly. EPAS frees up power anyway, but you will need to modify or replace the kmember from an 11-14 car. Direct bolt in part, got mine for $45 at a local yard.
The hardest part is how you want to wire the pcm. With a 2010, a rear damaged doner 11-14 car would allow you to just swap harnesses and make it practically plug&play, but I am not sure.
I chose to custom wire mine, repinning the PCM to body connector. Long and tedious way to do it, but I did not have to rip out the interior to swap harnesses. My stock fuel system works fine and is untouched. IIRC, it is just 2 wires at the pcm that needed to be connected, fuel pump control and monitor circuits.
As for installing the engine in, its a direct bolt in. The only thing that needed to be custom made is the low pressure AC hose from the dryer to the compressor.
Ask anything you want, just keep in mind, I did this swap 4 and 1/2 years ago. lol And I have NO ABS, so I don't know how the coyote PCM will play with the factory ABS.
