here is a diagram of how I have it wired. The green wire from the VC-25 goes into some taped up wires from the battery so I'm not sure if the is a positive or negative, but I think it is negative. From my under standing the VC-25 is basically a electronic pressure switch and relay. So my thought is that something happened to the unit when i accidentally touched wires and burnt out the key-fob switch. I tried taking apart the VC-25 to look at the board, but that thing is clued to the housing and will not budge.
