Grey connector goes to the TAC. Black connector I can't tell, where do all the wires its attached to go?
I ended up with 7 fuses on my harness. I know Lt1swap only shows 4, but I didn't intergrate any circuits and everything in my harness is wired to the same amp fuse it was designed to use.
This is just a pic of my notes, never intended on posting this so hope you can read it

. The dots represent the fuses and all the things down the left side are the circuits that need power.
