Crimp! If you want to have a
disconnect, and it is in the engine compartment (or somewhere where the temp is
somewhat different than at the data module) use the appropriate connector plug
from Omega.
And maybe others can back me up on
getting Tracy to go to a crimp pin D-sub at the EM2 25-pin plug rather than the
solder-socket. I found soldering TC wire to the pins is a real challenge
(even needed some additional flux, and now I worry about corrosion); and
soldering those materials doesn’t really form a bond anyway (no eutectic
as with copper or silver), just a mechanical bond.
