All Excursions use the 2-valve design. Even the 2005 which is the first year of the 3v in the pickups.
Don't plan on doing it, just wondered if the electronics would match up.
I'm pretty sure you have to swap harnesses because the 3-valve has more sensors.
But.... 2005 also brought in CAN-BUS communications in the F (and E-series) gas motors. I'm not sure if the Excursion also got that electronics update. Swapping to CAN-BUS would also mean all new modules (Air-bag, PCM, ABS etc) so I'm not even sure its possible. I'm a little suspicious that maybe the Ex didn't get the 3-valve because it didn't get the CAN-BUS upgrade. It's probably way easier just to add a Supercharger! Or even the Banks PowerPack. The 2-valve with PowerPack pretty much matches the 3-valve output.
