You are welcome, Craig!
I was pretty much racing through the installation today, prior to leaving for work, so I don't have any photos yet. Hopefully tomorrow I can at least post one of the 4-Way harness where I tapped the power.
An additional observation; The wire I used is always hot. It does not switch off while cranking the engine. This is exactly what I wanted.
The ChargeGuard does just what they claim, passing power to my device when the engine is started, and disconnecting it after the user-set delay after engine shutdown. The delay on my model can be set for 15 minutes, or one to 15 hours in one hour increments. There is a pushbuton to start the cycle manually, without starting the engine.
Right now, I have the delay set for three hours. Considering the lawn-tractor-like battery in the Fit, I may connect up a ScopeMeter to log Amp hour and battery voltage drain over that period, just to be sure.
Some of the benefits of this system over an ignition-switched system;
Track log recording is continuous. It does not start a new log after evey stop at the Post Office, gas station, and campground check-in.
Trip data is more accurate, including "Stopped Time" and "Trip Average Speed".
Satellite acquisition does not need to re-start after brief stops.
I can press the manual override switch to start the unit without having to turn the key.
Overall, I am very pleased with the arrangement. I just wish it hadn't taken almost a year to install!
