Fun linguistic quirk: Americans tend to call it a "wiring harness", whereas Brits prefer "loom"

As a result of this and the child comments…

As an Australian. I often find myself saying things like “the wiring hardness, or loom, or cable, or whatever were calling it this week”.

Exasperated by living in a state other than the one I grew up in. South Australians are often easily spotted by their pronunciation of certain words.

i wish the ui on those things was more visually appealing. between the cheap looking gloss finish on the display itself and the unextraordinary ui, it's just kinda blah. one can have a debate about to screen or not to screen or whether to use vfd displays or whatever and i get the importance of cost control but it should look good and it really doesn't. the graphic of the car looks like a cartoon.

It's glass...

And, of course, Germans have a dedicated composite noun for it: Kabelbaum (literal translation: cable tree).

I always like to point out that Germans don’t, in fact, have a word for everything.

It’s just a phrase or sentence with spaces removed.

> Turns out that actual cars don’t have individual cables. Instead they have these big “looms”, which bundle many cables from a nearby area into a single harness. This is the reason why I could not find the individual cable earlier. They simply don’t manufacture it. I was really surprised to read this at the end of the article -- how could someone be this deep into a project of this depth and not realize this?! Not o…

> and to Tesla's credit they have amazing free docs Not to Tesla's credit, they had to be dragged kicking and screaming into it (primarily by Massachusetts) and their right to repair legislation through a solid chunk of malicious compliance: 1. When told that they had to have a site for people to order parts, Tesla put up a site that had every single item as "Call us", including the most simple of bolts. And when a f…

Tesla treated the service manual like congress treats certain recently surfaced files.

Software people tend to overestimate their knowledge of other disciplines, writing it off as "easy" or work beneath them. Being overpaid compared to your peers certainly doesn't help dispel this feeling. Some people have built entire careers around designing wire looms.

There's a reason that John Salvatier's 'Reality Has A Surprising Amount of Detail' blog entry is so evergreen on this forum.

I used to work for a company that made third party scan tools. We had racks of ecus disconnected from the car with just a diagnostic connector and power. nothing got to a real car without first trying it on the rack. I remember on time we figured out a bmw (pre obdii) had the bytes offset from the standard documentation (it was a semi-standard protocol that some other cars used at the time), we went from we communica…

Diagnostic Trouble Codes?

Yes.

I'm sure you're an expert, pro at everything.

EVS have actually managed to reduce the number of wire bundles (mostly due to switching to Ethernet instead of CAN Bus)
