If you already have a wire at the dash that runs to the back cabinet,
why not cut that wire at the dash and use it to pull two wires to the
back cabinet? Just tape (best to solder) the two wires to the pulling
wire as flat as possible and it will most likely (fingers crossed)
find its way down the path of the existing wire. Bon chance.
