Handling Components and Connectors
Harness Connectors
The harness connectors used throughout the vehicle are designed to positively lock into place.
Harness Connector
Typical wiring harness connector. Push on wire lock (arrow) and gently pull on connector to release.
CAUTION: To disconnect, pull only on the connector body. Never pull on the wires themselves.
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.
Alligator-clip Test Leads With Flat Connectors
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 include special adapters which can be used to make test connections safely and prevent
connector damage. See 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.
