As I posted, I plan to use the Delphi GT480 series connector, which is rated at 42 amps. Where did you source the 3 cavity Anderson connectors and terminals?

In most, but not all, of the failures I've seen the fans have been set to run at 100% by a custom tune instead of the factory 90%.

Got my parts from Mouser. Detailed parts list is in my corvette forum thread. Total cost was less than $35 for the connectors and terminals.
