For example, today I was puzzling over why PIN 11 was free on the connector to the Lamp Control Module (LCM) when the instructions claimed that PIN 1 should be free. I figured the author made a typo but decided to call Eric just to be sure. He quickly deduced that the rectangular box with 3 connectors that I was fiddling with was not the LCM but was, in fact, the main computer! I might have figured that out on my own when the other two connector pinouts also didn't match the instructions, but nonetheless, Eric saved me some time and possibly some smoke. :-)
After going through this exercise, I've found places where the instructions could be improved. I'll work on that when I return next week from the COMNET trade show.
In the meantime, here are a couple photos of the difference between regular running lights and rear fog lights:
Ordinary running lights
Rear fog lights activated
This photo illustrates why it is not a good idea to hardwire the rear fog lights to the running lights as some have suggested. These things are pretty dazzling in clear weather.
On the E39s built after 3/99, it is not possible to accidently leave the rear fogs on all the time. If you shut your car off while the rear fogs are turned on, the next time you start up, the rear fogs (and dashboard indicator) will NOT be lighted. You must turn the switch to off and then back to the rear fog setting again. That's an excellent way to prevent people from running around with these things on all the time. I wish Volvo and Jaguar would do the same.
