Single Wire Seals, Installing

Procedure

  Note

  • Single wire seals prevent the penetration of water and dirt into the connector housing. They are installed, for example, in the engine compartment and must be reinstalled after a repair.
  • Single wire seal is crimped on at the factory together with contact on the wire, this is not the case for repair wires. The single wire seal must be slid onto the wire before crimping the repair wire.
  • Single wire seals must always fit with the repair wire cross-section. Outer circumference of single wire seal is aligned according to chamber circumference of the connector housing. Perform assembly using only the assembly tool with correct fit.

- Put single wire seal -A- onto free end of repair wire.

  • When doing this, the single wire seal small diameter must point toward the connector housing.

A97-0087

- Slide the single wire seal -A- onto the repair wire up to the connector housing and then into the housing as far as the stop using the appropriate assembly tool -B-.

A97-0088

- Shorten the repair wire and the vehicle-specific wiring harness single wire as needed using the Wiring Harness Repair Set - Wire Strippers -VAS1978/3-.

- Crimp the stripped ends of repair wire and single wire of vehicle-specific wiring harness using crimping pliers and a crimping pliers. Refer to → Chapter "0.22 mm 2 Wire, Repairing with Individual Crimp Connector" or → Chapter "Repairing a Wire 0.35 mm 2 or Greater with Individual Crimp Connector".
