Hi guys, I'm looking to buy the Mirrortap MTX-1015 so that I can connect my Uniden R3 radar detector to my rear view mirror for power 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 a reference. Thanks in advance!
