If not too late, yes you want the 2010 Denso alternator. They are more expensive but should last a lot longer, hopefully forever. Department of Boost had them for sale a while back, not sure if they still do.

The battery already has a ground wire, connected to the chassis; otherwise nothing would work . . . I am not sure what the forums were talking about there, maybe upgrading it to heavier cable or making a better connection on the end? For sure you want to make sure that all of the major connections are in good shape (mainly: clean and tight).

There are two (2) ground wires from the battery: One to the strut tower at the passenger side and the second to the starter. There is a third ground (ribbon cable) from the rear of the block to the top ledge at the firewall on the driver side.
Along with the power wire from the battery to the alternator, the forums refer to these as the "Big Three" and upgrade to a heavier gauge wire when running a lot of electronics and higher amp alternator. Additional ground wires (Big Five) typically involve the alternator to chassis and heads to chassis. I don't recommend the Big Five unless you're absolutely certain how your electronics are connected as you might cause a ground fault loop and do serious damage. Leave that to the pros.

Welcome!
Although Not Exactly What You Are Asking For this Link and Pdf. Maybe Helpful. The Pdf. Shows an S550 But The Kit is Also Listed For S-197 Applications

2005-2009 alternator issues.
go to American Muscle and order the 230 amp alternator and upgraded bigger gauge positive cable. Problem solved! Did this on my 2006 GT and 2007 GT/CS.
