I was putting the wiring back on my motor last night, which was removed 1 1/2 to 2 yrs ago, and I hit a snag. And just so y'all know its a 73 1.7. The wire in the first pic branches off w the wires that go to the dist and the cold enrichment injector. I had it labeled head sensor, the problem is I labeled the wire in the 2nd pic head sensor. The wire in the second pic comes out of the harness by itself and is closer to the sensor so I assume thats the 1 for the sensor. So where does the wire in the first pic go? Thanks in advance for any help.

Does it go to the thermo-time switch mounted under the plenum?

Ah yes! That has to be where it goes. I guess its easy to not even see that one when its buried under everything. Thanks Doug!
