Haltech F3

[Sandy]

I have the haltech, and I beleive the sensor are the National LM335Z style
parts mounted in a brass fitting. The one used for the MAT sensor has the
National emblem showing, and that's what I assume it is. I'm not sure why
they used those instead of a regular automotive sensor, I'm sure their was
as reason, but one can only guess.
