With a wiring project like this it's funny how, as you get this deep in, it gets both easier and harder...
Easier as you develop the "big picture" in your head, you start to see how everything pieces together and it all begins to make sense
Harder because of the sheer quantity of things to keep track of... Man, how many pages of notes do you have by now??
I've done a couple of harnes blend jobs, but if we combined both of em together they still wouldn't equal half of what you're dealing with here- my most recent was the result of dropping a 1976 22r into a 1970 Toyota 4x4 replacing a 20r. Wonderful lil' truck, lotsa fun! Anyway, the harness work was stupid easy compared to what you're doing. Just enough that I really appreciate the labor of love you're putting out here.
Good job man- keep after it! The thing we both have in common- one wire at a time, one connection at a time, one sensor at a time and so on... Dozens and more, or just a dozen-ish, it's still one bit at a time
Oh, and yours will be a shit ton more impressive when done
