I did not buy the one you suggested. I bought the Harmony Audio HA-709401 adapter. Do you if they are wired properly?
I spliced color for color and everything works fine. Are you saying that I should switch the red and yellow wires to keep battery from going dead??? It works fine on ACC and engine on.
