Idiots
The installation in question was done by an allegedly competent avionic shop and I quite agree with your comment about it being done by an idiot - no proper testing, or some of the issues would have been found. However, they had wired to an FAA approved AML which did not reflect the aircraft interface and which was which was ultimately incorrect!
I'm sure every avionic installer in the UK and US who can operate a crimp tool will be delighted to know you think of them as idiots. Whilst they may not be highly knowledgeable about component level design, there is nevertheless a decent level of skill required to produce an accurate, functional, reliable and airworthy installation of today's complex avionics. I assume you'll never want to go near any European shop to have work done?
I consider this discussion over.
