[anothercrazycooter]

So I almost done installing a new engine in my 4 Runner and I cannot for the life of me figure out what this connector hooks to.  Here are the specs on my runner and some pics.  Let me know what it is thanks.

-1989 1st get 4Runner
-22re
-smog stuff was removed because it is not required in Indiana (is this part of the smog system)
-connector comes out of the wire harness in the middle of the intake manifold
-other wires coming from the same spot are the temp sensor wire, knock sensor wire, and oil pressure sensor wire.

Where does this wire hook up?

[Sparkplug]

On all 22re i have worked on, there is a plug in the middle of the intake, near the top, that is not used, but its wihite from wat i remember, with 2 spots like that one, prob for cruise control or sumthin
