FLIGHT HARNESS DESIGN
The build responsibility for the harnesses between the Standard Offering Interface and Payload (hereafter referred to as
“Customer-specific harnessing) will be specified as part of the Payload-specific ICD. In general, any harness containing deploy signals will be built by SpaceX, while any harness that exclusively has breakwire and/or umbilical signals will be built by the Customer. For Customer-specific harnessing built by SpaceX, SpaceX may require the Customer to send SpaceX the flight connectors at the Payload interface. For Customer-specific harnessing built by the Customer, SpaceX will send the Customer the required flight connectors to interface at the Standard Offering Interface. Customer-specific harnessing built by the Customer must be designed and builtin accordance with the Wire Harness Build Guide provided by SpaceX as part of the mission integration process. In all instances, details of the harness design, including length and routing path, will be determined through routing review meetings between SpaceX and the Customer and documented as part of the Payload-specific ICD.

CONNECTIVITY DURING PAYLOAD PROCESSING
SpaceX accommodates electrical connectivity between Customer EGSE and the Payload during standalone processing. Electrical interfaces will not be available during SpaceX adapter mate, encapsulation, Launch Vehicle integration, and rollout operations. Between these steps Customer may elect additional connectivity as an optional service as described in Table 4-4.
Table 4-4: Payload Electrical Interface Connectivity
Phase Interface Connection Note Payload processing (in PPF) Customer cables directly to Payload Included Mate (in PPF) None
-- Encapsulated (in PPF) Customer cables to PPF junction box or equivalent interface Optional Service Transport to hangar None
--
Pre-integration (in Hangar) None
--
LV integration (in Hangar) None
-- on TE (in Hangar) Customer cables to hangar junction box or equivalent interface Optional Service
Rollout None
-- On pad Customer cables to pad junction box or equivalent interface Optional Service Flight Separation initiation and indication only Included The Launch Vehicle does not provide power to Rideshare Payloads during Launch operations. Payload batteries must be switched off during Launch. An exception maybe made for batteries in standby mode with closed circuit architecture if test results provided to SpaceX verify spurious emissions meet the requirements defined in Section 3.3.7.
