986 Tuning Options

[78F350]

That makes a lot more sense of what you are asking for.
Even though it's a V8 swap, you may glean some useful info from this page: https://sites.google.com/view/boxsterv8swap/home

I have scrapped a few 986s and can probably find enough old wiring harness parts for you to assemble your own adapter if you are up to it.

Also, I think that somewhere in this thread, truegearhead mentions having a custom harness made for his twin turbo V8 swap. You could contact him and see if they can fabricate one for your needs. https://986forum.com/forums/performance-technical-chat/77421-time-trial-build-thread-aero-widebody-any-other-nonsense.html

The Engine side of the EMU Black should be pretty simple. Getting wired to the rest of the car for full function will be a bit more complicated.
