## ⚠️ Common Signs of Failure

-   Intermittent electrical or sensor fault
-   Water or corrosion inside the connector
-   Broken locking or retaining feature
-   Harness abrasion at the opening

## 🛠️ Service Notes

-   Isolate the batteries first, and note which way the housing sits and how the harness runs into it before anything is disturbed
-   Move terminals across one at a time into the same cavity positions, releasing each locking tab with a proper extraction tool rather than pulling on the wire
-   Check every terminal clicks fully home and locks before the housing is closed; a terminal that is not seated will back out under vibration
-   Make sure all seals, grommets and blanking plugs are present and undamaged, and leave unused cavities plugged so the housing keeps water out
-   Support and route the harness so nothing hangs on the housing, and check the connection is dry after the first run
