I've hit a snag installing this new HU. Wtf is that and why is it installed in my car?? For some reason I couldn't get my old HU to come on unless I left that contraption in there. When I took apart the dash to order a new kit, i found that and tried to remove it while cleaning up the wires. i thot it was some cheap noise filter or something? Well the HU failed to work unless it was installed. Now after removing it tonight, I can't remember where it went. Tried the gound and constant, then ground and acc but nothing. Now I cant power either radio. What am i missing here?? Shouldn't I be able to run straight to the factory wires and get power? It just worked a few days ago...I looked to make sure what wires were correct and I think I've got them right.
12V constant- blue/red
12V switched- black/yellow
Ground- brown
