Yes, no doubt that you can.
Call Traxide, tell Tim you are installing into a V8 LR4. He will send you and LR3 kit.
Remove TC ECU from plastic enclosure. Discard plastic enclosure. Move TC ECU under brake piping, attach to horn bracket.
Install kit. Buy group 34 battery, Optima or Odyssey. The Optima is an easier fit.
Bob's your uncle...
I don't have a pic of my odyssey in the engine bay on this phone, but here is what you get to pre-battery. Note the TC ECU under the brake lines, mounted to the horn bracket (horn on backside, barely visible). TC ECU is mounted using some aluminum angle cut as brackets (you can see this as well in the pic). The rest of the "install" is per the Traxide kit instructions.
