Engine looks the same as mine, except that they appear to have moved the injector wiring harness connectors to under the new (plastic?) black cover...
Intake horn is in the same place. I'm curious - did the part number for the fuel filter change?
Also, for those who really like the new headlights I'd bet you could swap fenders and headlight assemblies with a 2003-2005 model truck. Someone at a dealer might be able to verify whether the fasteners appear to be in the same locations...
Oh, looks like no more gauge-friendly dash cubby.
