Hi guys, I'm looking to buy the Mirrortap MTX-1015 so that I can power my Uniden R3 radar detector through my rear view mirror in my 2010 Mustang. I'm having trouble identifying which input to plug in for power and which to plug in for the ground. Would anybody know the answer to this? I provided a photo of the inputs behind my rear view mirror for reference. Thanks in advance!
