J 38125-B  Terminal Repair Kit

The supplemental inflatable restraint (SIR) system/supplemental restraint system (SRS) requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working with the SIR/SRS system wiring, and the wiring components (such as connectors and terminals).

Important:  Do not use the terminals in the kit in order to replace damaged SIR/SRS system terminals unless specifically indicated by the terminal package.

The tool kit J 38125-B  contains the following items:

  • Special sealed splices - in order to repair the SIR/SRS system wiring
  • A wire stripping tool
  • A special crimping tool
  • A heat torch
  • An instruction manual

The sealed splices 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 J 38125-B  also serves as a generic terminal repair kit. The kit contains the following items:

  • A large sampling of common electrical terminals
  • The correct tools in order to attach the terminals to the wires
  • The correct tools in order to remove the terminals from the connectors
