I installed new power top pump in my 67 convrt and the switch seemed to operate intermitantly, so I installed an new switch, still same problem in fact now the up direction doesn't seem to work at all. I now wonder if the switch was origially wired right? Does anyone have a schematic showing how this should be wired in? My manuals don't seem to show this part of the wiring. Thanks in advance for any help Louie
