I have a couple other loose random wires and vacuum hoses. Here is a connector with a green wire and a short black wire with ring terminal. This exits the firewall on the passenger side near the AC box.
And here is a random vacuum line with a T in it that is just open to atmosphere.
For the record, this in AC truck and I'm assuming some of these wires are related, but all of that stuff was disconnected and missing when I bought it. Also, all of the emissions gear was gone as well. Trying to clean things up and get everything working again.
