I would like to get all of the parts Necessary to put power windows in my 86, however, this may sound a little strange, but I only want to do it to the passenger side, and wire up a switch on the dash to be able to control it from the driver side as well. I would like to keep the manual window on the driver side. Our concrete trucks are this way, and I preferred over all other configurations. Are the plugs for the harness already there somewhere in the door? What all parts will I need?
