Correct, but I want to know what the pinout is. I see 3 pins where it is marked power supply, but dont know which is 12v/ground.

So I bought a used D3 with the bluetooth adapter, however there is no power harness.

It can be purchased from Pioneer but its on backorder until May...so I want to make my own. Looking at the picture of the adapter below, I'm assuming the very left pin is +12 constant, middle is nothing, and right side is ground? If anyone can confirm that would be great. Thanks
