OVERVIEW
Factory five-pin coupling housing for the engine harness
8K0-973-805 is the Genuine VW/Audi black five-pin connector housing used at the assigned engine compartment harness coupling on the confirmed S5 V8 Coupe application below.
The housing shape, keying and locking arrangement are part of the original connection design. It must match the specific harness coupling; another five-pin connector can have a different terminal layout or mating profile.
Technical details
- Complete factory number: 8K0-973-805.
- Factory specification: 5-pin; black; engine compartment harness coupling housing.
- Design: molded flat connector housing with keyed mating profile.
- Quantity supplied: one individual connector housing.
This listing supplies the individual housing shown. It does not supply a complete wiring harness or a prewired repair lead. Select the required terminals, repair wires and mating parts separately to the vehicle wiring specification.
Common reasons to replace
- The housing is cracked or physically damaged.
- The connector locking feature is damaged.
- Heat damage has distorted the shell.
- The terminal-retaining arrangement no longer secures the contacts.
- An incorrect or missing housing was identified during wiring repair.
Inspect the terminals, seals, mating housing and wire insulation. Circuit faults can originate in damaged contacts or wiring even when the shell looks intact. Replacing the housing alone does not repair those faults.
Vehicle fitment
Confirm the five-pin engine-harness coupling, V8 installation PR code and original housing number. Body and engine restrictions matter for this connection.

Installation guidance
Follow the factory wiring repair procedure. Isolate power where instructed, record the original cavity assignments and use the correct terminal-release tools and specified repair wires. Do not force terminals or interchange pin positions.
Confirm that the contacts and secondary locks seat correctly and that the mating connector engages securely. Route the harness without tension and perform the prescribed circuit checks.
