I am getting very close to having this "basket case" together. It has sat since 99! Anyway, I have two leads with blade type connectors that go on sensors. One has a green wire with a red stripe, and one has a yellow wire with a green stripe. I am not sure which one goes to the sending unit on the thermostat housing cap and which one goes to the lower sensor that also appears also to be in the cooling system. Also, I have a small hose that comes from the bottom of the black connector that hooks onto the inlet (which comes from the air filter) to the turbo. Can't see where it connects either. 88 t auto
