| Thank you for posting this article. I'm in charge of the
| electronics package of a Formula SAE team, and our wiring
| harnesses follow many of the practices found in this guide. I
| personally have been astounded by the fact that many of the
| assumptions we make with hobbyist-grade electronics go out the
| window when designing for motorsports. You can expect to find
| that at some point, water/fuel/oil/brake fluid will fall on your
| wiring. Seemingly sturdy connections will only misbehave under
| specific conditions such as high-speed cornering, making them
| difficult to debug.
|
| Another thing I've also found shocking is how quickly the
| expenses can rack up. The Deutsch Autosport connectors listed in
| the article almost universally start at around $30-40 per
| connector. Heatshrink products are also very pricey, with the
| additional downside that if you make a mistake in the
| manufacturing process there is no way to re-use them once they've
| been cut off.
