^^^ Sorry for not clarifying enough; I was referring to the wiring/electrical stuff. VSS, neutral position switch, possibly ABS or cruise control (although it looks like this build is way beyond any of those things hahaha), and just dealing with the TCU in general.
I've found a bit of info on this topic (Dyne's H6 swap on rs25.com, etc.), but it's all scattered about. Any info helps, really, even if it's just confirmation of things I've already seen.
Haha just doing my research whilst saving up my monies
