The 10mm wrench is a better solution than some flimsy junction that might accidentally work loose during operation--losing the return path would cause momumental ECU damage.
I appreciate the 'working loose
' possibility, and used a lockwasher on the knob I installed.
And I got a data point today on the 'ECU damage
' concern, as I had a problem that caused the negative terminal clamp to come loose from the battery while driving. (It was NOT the quick-disconnect knob that came loose.)
The good news is that the car ran fine to the point of me turning it off, then of course it would not start back up until I reconnected the clamp to the battery terminal. 12V (nominal) continued to be available via the DC-DC converter. All that went wrong was the 12V battery wasn't being topped up for a portion of that drive, and of course all the trip-meter data and dash settings were lost upon powering off.
