mounting bolt, and ground other end under any metal
body bolt that is clean of print and rust. Compressor must
be grounded. (See Figure 1).
2. To secure the compressor, drill a 3/16-inch hole. Mount
the compressor vertically (air outlets on top). Install the
head of the bolt into the slot on the compressor’s
housing. Secure the compressor to the vehicle using the
lock washer/nut provided (Figure 1).
