Hi,
I just got this 2.0 with dual carbs. While examining the engine bay area. I see this wire coming out of the hole in the tin that covers the head. It's not connected and just hanging there. Where does that plug in and is it a head temp wire? I can't seem to see where that would connect to. And if it doesn't have to connect anywhere. Should I tape off the end so there is no short? Thanks!!!!! I posted some pics.   Attached image(s)

Tuck it away. It is not used or needed with carbs.

Yes. It is an important part of the fuel injection system. D-Jet used basically the same thing for the same reason--to see when the engine was cold or when it was warmed up.

Your car being a 73 may have the very desirable (unique) CHT sensor.
And no, you don’t need it with carbs |
