Ok so really the only things i have questions on are the gray wire in the second pic, just a single spade female connector, and the second half of the coil. I cant see any wires missing on the harness itself... Isnt that second connector part of the main harness? Also, where do those wires go to, if i had to splice it in?

Few more connectors, a few in the cab, one in the engine bay. I don't think they are anything important. I did cut a bit of the harness out that went to things I knew I wasn't going to use, so I don't remember if these are needed or not
I still cant for the life of me figure out WHERE THE HELL the other connector for the coil went
What does it get wired to?
