Wire in question circled in green (same wire as picture 1) but I pulled the wire circled in #2 off of its tab that I also circled in red, trying to figure out where the wire circled in green goes. Hopefully that makes sense.
Any ideas? I'm just not seeing an obvious spade connection that the black wire would have popped off of.
Most, but not all, starters have two spade connections on them. Visibility isn't the best as you see, but it should be down there. The one wire is for start and the other goes to the ballast relay for the ignition to get a hotter spark at starting and to the ECU to provide starting enrichment. Usually the two spade terminals on the solenoid are at a 90 degree angle to each other.
