So I am trying to hardwire my V1 (2003 Jeep). I am using the kit from V1 and a add-a-fuse mini which is plugged into a 10 amp radio fuse, I then added a 3 amp fuse into the other slot. I clipped/stripped the end of both red wires on the add-a-fuse and the red wire on from the V1 kit and wire-nutted them together. My question is where to ground the black wire from the V1 kit. I have tried several screws but they are all screwed into plastic so I am having trouble finding something to ground to which I think is why it is not powering up. The radio is still working but the V1 remains powerless. I have checked all fuses and they all look good......you guys have any thoughts, is there a simpler way to hardwire these? Not too familiar which automotive electrical so any ideas would be appreciated.
