Connector Handling
WARNING: This page is about a different car, the 2004 Lexus GS 430 and 2004 Lexus GS 300. However, it is still accessible from the selected car via links, so may be relevant.
When inserting tester probes into a connector, insert them from the rear of the connector. When necessary, use mini test leads.
For water resistant connectors which cannot be accessed from behind, take good care not to deform the connector terminals.
