SFI 16.5/FIA Standard for DE Harnesses

[larrybard]

For DE -- NOT for club racing -- may a new 5 or 6 point harness be installed and used for 5 years if it conforms to SFI 16.5 standards only (and has no indication that it also conforms to FIA standards)? I understand that the SCCA may permit SFI 16.5 harnesses to be used only for 2 years (but FIA harnesses for 5 years).

Thank you

Larry
