2003 6.0L Injector Harness

[428F250]

Can I replace the 2003 injector harness (3C3Z 9D93 AA / 1843796C92) with the 2005-2007 harness (5C3Z-9D930-AA / 1870390C91). It seems to me that they should have the same pinouts. The newer harness is about 1/2 the price.

Thanks,
Jay

The ICP sensor wire is going to be in the wrong spot. The routing is way different around the filter housings but that should be self explanitory. you may have a couple conflicting intake manifold studs in the wrong spots also

Looking at the wiring diagram, it doesn't look like the ICP sensor wiring is part of the injector harness. I could be wrong, but it looks like the injector harness just runs between the injectors and connectors X1 and X2 on the FICM.

sorry I missed the injector harness part
