It could be that that many of the damaged ECU's could have escaped water damage with two drains rather than one.-

You are confusing upper drains with lower drains.

ALL 75's have 2 lower drains.
From mid 2003ish the driver's side upper drain was replaced with a grommet.

The upper drains are not related to problems with ECU !
