Are other fuel rails/injectors compatible.....

With the 2002 4.2?

Found a rail with injectors from a 2004 Rainier and I'm curious if it's compatible with my 02. Reason I ask is the different ECM.

injector part 12569573 fits 2002-2004. Should be no difference in rail.

Cool. Main part of the rig I was concerned about is the harness. Does all look to be the same though based on the pic.
