MAKING TEST CONNECTIONS
Many electrical troubleshooting tests will require hooking up to wiring harness connectors, or socket connectors on electrical components. Test connections made carelessly or without proper tools can easily damage the connectors, causing poor connections and future problems.

To avoid connector damage, test connections to wiring harness connectors must be made using small, flat-blade terminals which will mate properly with the connectors. The Special Tools recommended by Audi include special adapters which can be used to make test connections safely and prevent connector damage. Tools and Equipment

All test connections to harness connectors should be made using the proper adapter or correct size flat connectors that will not deform the connector cavities.

WIRING HARNESS REPAIRS
When repairing wiring harnesses, use only high-quality electrical connectors suitable for use with electronic components.

To make connections, use crimping pliers that make a "W"-type crimp. Only this type of crimp provides the necessary mechanical strength.
