Special Tools
- EL-38125-10 Splice Sleeve Crimping Tool
- DuraSeal splice sleeves
- A wire stripping tool
For equivalent regional tools, refer to Special Tools .
The DuraSeal splice sleeves have the following 2 critical features:
- A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside.
- A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits.
The GM Local Area Network (GMLAN) System requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working on GMLAN connectors and terminals.
