EFI control

[Shirley, Mark R]

OK, I guess I look at the exterior and think if the box looks this bad, 
did they take the time to get the innards right?  You can determine a 
persons work ethic by looking at almost any of their work.  
As far as beauty being skin deep, I don't think that applies to anything 
but human beings, as a general rule.  As far as the harnesses, I can SEE
those on the website, and I KNOW what they are made of.  To be fair though,
it IS VERY difficult for a non-OEM to produce harnesses that meet
OEM-type specs.  Harness suppliers aren't setup to provide quantities lower
than 30,000 or so.  And there is a real dirge of quality weatherproof ECM
connections available.  The only one I am aware of is Packard's metripak 
series, and they are pull to seat (read pain-in-the-*ss to assemble).
All the rest are proprietary, and not for sale to general public.

No, and Yes,
No problem.
I think the design and execution of the current pcms is at least elegant.
But, it didn't happen over night, and an aftermarket companies have no where
near the talent that say GM does.   But, that doesn't mean there can't be
other answers for other applications.  All things being Equal, I'd rather
forgo pretty packaging.  Pretty like they say is skin deep.  Well executed,
reliable, are all seperate issues.
