I was under the impression the the IC is shown there, right behind the valance with the black plastic top.
If there's not one already, i'm assuming CXracing or other cheap substitute would eventually make a kit for the 3.5EB F150. Or someone makes brackets/adapters etc to retrofit a common universal IC. The current aftermarket EB IC's do look a bit more complex, oe fittings, separate **** for the BOVs on some. Really haven't looked into this too much though... Universal would do well for the street trucks, though build on cheapo ones may not survive abuse. $150 vs $1500, so im sure someone will be our guinea pig
