I'm pretty sure you'll have to get a cobra wiring harness and extend it a bit. For the intake, some people have been working on trying to get the new Boss 302 intakes to fit, but it takes some fabrication. There's also a user on the corral forums who sells a whole 5.4 swap kit, which makes everything basically plug and play.

It should be the exact same harness with the exception of IMRC plugs if it's B head (don't know if 5.4's are b or c head).

Turns out if it's a Navigator engine then you should be good with your regular harness! My bad.

I think you'll still need to extend it though.

Well seems like the wiring harness from my gt works on my navigator and its very similar. But the fuel injector plugs on my stock harness wont fit in the 5.4 4v injectors. Do i just splice them and stick the 5.4 injectors on the stock harness? Thats what i was thinking. Yeah my hood will need to be replaced haha. No way that navigator intake would fit under my hood unless i cut a hole in the middle of it.

Im also getting mixed answers for the radiator. I read the 4.6 radiator from the gt would work fine for the 5.4 but then im also reading that you would have to replace all the tubes and the radiator. Can some one clear that up for me? Would I have to get a 5.4 radiator or could i get a 4.6 4v radiator? and tubings for it?

Do you know the user who sells the 5.4 swap kits? That would awesome if i could find something like that.
