Here is what is on their site presently (red added ):
Harness Systems
If the participant chooses to install a five- or six-point driving harness, several changes to the automobile must be made to create a safe occupant restraint system. Harnesses must:
Include an antisubmarine strap.
Have all harness attachment points secured/mounted in an approved manner consistent with the manufacturer’s instructions.
Be used in conjunction with a seat that has the supplied routing holes for the shoulder and antisubmarine belts.
Have the shoulder straps mounted at 90 degrees to the axis of your spine or at most 40 degrees down from horizontal.
The participant should BE AWARE that the addition of such a seat and harness system results in the occupant being fastened upright in the vehicle. Therefore, in order to have a COMPLETE SYSTEM, a properly padded roll bar or roll cage and an approved Head and Neck Restraint System (HANS) device are strongly encouraged and highly recommended. The use of such a harness system without roll protection and HANS may result in an unsafe environment and is not a COMPLETE SYSTEM. Roll bars or cages and their installation must meet PCA Club Racing Standards
When using a head and neck restraint device, it must meet the standards of either SFI 38.1 or FIA 8858. It is recommended that one follow the SFI Recertification process for the head and neck restraint device. The instructions for this can be found on the device. Additionally, it is recommended that the straps be replaced every five years.Due to UV degradation and wear, the harness webbing must be replaced every five years.
