Are you sure that the reason automobile manufacturers use connectors
is because they believe a connector is more reliable than a properly
done solder joint?


No, it also has to do with servicability, which is another reason
-not- to solder the modules together.

Now.... do you have an LEGITIMATE concerns or are you just trolling?


You actually suggested that for reliability reasons a connector is
preferred over a proper solder joint.

A quote from you:

" Interconnection wires that are soldered have a high rate of
failure in abusive environments. That's why auto manufacturers use
connectors, even under the hood"

Give us a break. When practical a properly done solder joint is always
more reliable than a connector.
