Have a couple of questions. Was changing the oil in my 1999 Supra today and noticed a loose wire close to what I assume is the thermostat housing (someone correct me if I am wrong). The loose wire comes right out of the same place with another wire that is connected to what I think might be a temp sender or something. Also to remove the thermostat housing do you have to remove what I think might be called the throttle body spacer? Here are some pictures. All help would be apreciated.
