Hi Doug,

I bought the P-110 EGT probes from Aircraft Spruce.  These have 1/4 tab
connectors about 1 foot from the probe.  The Micro-1000 probes are
about 1/2 the price of the P-110s.  For some reason I didn't find them
back when I ordered.

I plan on using faston connectors crimped to type K thermocouple lead
all the way from there to my EM-2 which will have crimp on pins for D
connector.  Each discontinuity will introduce some error, but it will
be small compared to the EGT you are measuring.  Any EGT probe should
work OK.  Mine are located about 1.5 inches from the exhaust port.  I
should be able to report on their survivability in another month or two.
