Hello,
I want to install an "access-a-fuse" in my 1992 ford taurus fuse box to hook my scanner up to. Does anyone know if the left or right side of the fuse box is the hot/load side? Thanks in advance!

Do you have a multimeter or test light? If so, clip one end of either tool to a good clean metal ground, remove the fuse from block that you'd like to use, then probe both terminals in the fuse panel and which ever one cause the light to light or the DMM on Vdc to give a reading of battery voltage is the hot terminal.
