You really need to get a wiring diagram out, and look.  There are
sometimes small but meaningful changes from ecm to ecm.  They
are not the same.  In the passenger car versions they use a IAT.
Also, the tables will be moved around some I beleive.  If you want
to tinker with a 747 you need to have a 747.  Some of the advanced
guys can play some games with adapations, but if your just starting
out learn the baxics first.

I would also appreciate
