vehicle framing member.

Failure to do so will
void warranty of certain
electrical components.

Position and secure
ground cable clear

Ground Cable Corrosion:

When mounting ground
cables, remove undercoat­ing, dirt, rust, etc. from
framing member around
mounting holes (minimum
5/8” diameter area). Ap­ply protective coating to
mounting holes to prevent
corrosion. Failure to do

so will void warranty of
certain electrical compo­nents.
