So, you are measuring the fin root temperature?

Sounds nifty! Do you see any remarkable differences in the four readings?

Maybe you or others could clear up a nagging question or two:

Does this low thermocouple voltage work with all the VDO temp gauges or
just the CHT models. I inherited two VDO temp gauges from a PO and haven't
fiddled with them yet. Also in the box was a pin-type temp sensor for the
oil temp. Seems the Right Reverend Hoover was opposed to oil temp readings
from a tee at the idiot light hole. What'sthe (easy...) alternative?

I seem to recall some edict about using only thermocouple wire to run all
the way to the gauges. Something about the new dissimilar metal distorting
the readings?

Any clarifications are appreciated!
