ALL electronics throughout the installation must be individually fused with appropriate value fuses. Chassis-mounted fuses on electronic equipment satisfy this requirement. Competitors must present photographs of (or physical access to) fuses for in-dash equipment. All fuses (except for source units and processor units mounted in the dash of the vehicle) must be readily accessible within 30 seconds and be able to be replaced within the five minute breakdown period. A judge may request that this be demonstrated and will not award points if it cannot be done. Custom-motorized installation elecments must be individually fused, unless two or more motors are used to operate the same drawer or rack, in which case a single fuse for multiple motors is acceptable. Multiple lighting elements may be fused by a single fuse with no deductions
