Ring Terminal Harness Hook-Up
The correct way to connect a Ring Terminal Harness to the battery, with each appropriate lead connected to each battery post. The positive lead should be fused and as close as possible to the positive battery terminal.
Amazingly, forum threads manage to fill pages upon pages on the subject with recommendations of using the cigarette lighter, the OBD connector and even connecting the negative ring terminal harness lead to a ground point. Each of these can lead to possible slight losses due to potential drops so why bother?
The trouble with using the cigarette lighter in CANBUS cars is that it sometimes shuts down. Best to check that it doesn't.
The trouble with using the OBD connector is that I want that connector to work when I need it. Constant plugging in can affect the connector in time.
And on top of it, why would I want to run my charger cable past a door seal or through an open window.
