If you look at the schematic there is a #14 brown wire from the fuse panel to the switch (shown dash line) Make sure it was not in the other plug that you could not plug in. they may have used it to run the other controls. If you can't find it try running a fused wire from your Acc. switch to the terminal shown. If you have a ac cab and an ac controller the large holes will line up. You may have a controller from a later year. cant know without seeing it
