I can see here
that pin 8 of the ODB connector is keyed to ignition power, and is 10A. Normally, ODB devices are powered off pin 16.
I'm planning on buying an extension cable for LeafSpy Pro (recommended one here
), but I was wondering if anyone knows of any extension cables that have 8 wired to 16, so that my ODB II adapter would only be powered when the car is on.
Does anyone have, or know where someone would sell such a cable? I've searched but not been able to find one.
I know I could theoretically solder one on my own, but my soldering skills aren't great and it doesn't look like the connector ends can easily open in the ODB extension cable shown above.
