Oh sure that makes "some" sense. I'm happy to hear you made some progress. You sounded like you were getting a bit frustrated for awhile.
Unfortunately it "gets worse" The diagrams for the 90's EFI stuff are worse, and there's 10X as much wiring LOL The "always automatic" light switch (photocell controlled) are a real POS in my GMC and I haven't found a simple way to bypass that mess
