You don't really want this module. It is to circulate fuel
after engine off. Apparently it is only installed if a customer
complains about hot-restarts or something.

Yes, each app has a different ESC module. No, sorry don't
have the part number. Should still be able to order one
through Chevy dealer. JUst tell him it's for a 7.4l.
