That certainly looks like a ground symbol on pin 1. I agree that pins 3 & 4 seem to be 12v.
It’s pretty confusing to me why the charge pad needs all those connections. AFAIK, it’s not communicating with anything, just energizing a Qi charging pad.
I suppose I’ll test running 12v through pins...
I want to replace the Qi charging pad with something else and use the wiring harness to power it, so I need to understand the pinout for that wiring harness.
Can anyone here point me to that info? I bought a wiring schematic, but maybe I've forgotten more about electronics and schematics than I...
