I know about the blue wire on the head unit for the power antenna, but then that brings me back to the problem of getting to the head unit. The bracket removing devices were taken as a token to bestbuy (I had them install it 'cause I was lazy, and the took the removing clips). When I tried to remove, I nearly bent the retaining clips (the clips that keep the headunit in a nice flush position) and the head unit would slide whenever you'd press a button. I'm not sure if they actually tapped the blue wire from the head unit into the factory plug. I know when I intstalled my pioneer headunit into my Civic I just left it hanging 'cause it wasn't necessary. Like my Civic, my wife's Accord doesn't have a power antenna (it's a DX model). I guess I took the long way of asking, but, where in the trunk would this wire be? When we were back there looking for a hot, we checked 2 accessory plugs that were just hanging and only found the one constant hot that was mentioned earlier. Somehow that thing has power regardless of the car's accessories. Lemme know where this wire can be found. I apprecaite it.
