Mounting
For best results mount in a visible location. Use standard gauge mounting methods (in your
dashboard, or a gauge pod, or a gauge bracket) inside the passenger compartment. Although the
Timing Computer is treated to be weather resistant it CANNOT tolerate under-hood or on-hood
environments.
If you must bend the wires that come out of the back please observe the following guidelines.
