Stand alone 4.0 harness for 258

Swapping a 4.0 head onto a 258 and would like to swap the fuel injection in as well. I've done a LOT of searching but no luck.

Basically I'm trying to do this and make it work with a minimal amount of wiring.

Anyone done this? Are there any write-ups out there? What year would be the best for a donor harness?
