Couldn't I just do an EGR block-off/bypass? I'm assuming that when I pull the engine from the donor, it would be worthwhile to also pull the wiring harness as well?

I've been melting my brain trying to read the various 606 builds. Taking notes as I go along...hopefully I can get a good list going.

I just want to make sure I get all of the needed parts off of the donor vehicle(s).
