This doesn't look right...

Is there supposed to be another wire on the left side? What is that?

 

[racerx]

not unless

you want A/C

 

[Greg (in Conn)]

electrovalve for AC

allows extra air to be introduced to the engine at idle when the AC is on to raise idle speed.

There is a green wire

Same gauge as the black, and is usually taped to the black wire. Has the same looking connector as the black wire. The green wire comes out of the harness in that area and should NOT be confused with the (longer and heavier) green wire used with the Oxygen sensor.

But is there a wire missing?

I don't run the A/C, even though it was retrofitted
