Hi,
I'm not familiar with the schematics you have. I went back and looked up the manufacturer's schematic and attached them below. Normally, I don't use these because they are more confusing. However, if you look at the OEM schematic below, it shows the same as what my original one said. Yellow is from fuse C (40 amp) and goes to relay 2. From there, it goes to a pink/gray wire to relay 1. Next, it travels through a yellow/gray wire to the starter motor. The yellow/gray wire is the trigger wire to engage the starter motor. The pink/gray wires connection is indicated with a dashed line. In many cases, the position of one internal switch (relay in this case) will affect the position of another as between two relays. Such switches are called ganged switches and are symbolized by connecting them with a dashed line.
Not being there with you makes it much more difficult. However, all I have is the manufacturer's schematics. That is what I need to go with. If you have a jumper between the yellow wire to relay 2 and direct to relay 1, that is usually an indication that someone had installed a remote starter system. I can't guarantee it, but that is what I suspect. That would also explain why the wire/fuse was loose and fell out. Chances are when it was removed, they weren't too gentle with it. Again, that is only my theory. I wish I was there to help.
Let me know if this helps you in any way.
Take care of yourself,
Joe
