Toyota / Lexus 8-Pin Sunshade / Auto Parking / Stop Lamp Switch Connector – OEM 1746875-1 / 90980-12558 / 1376368-1
Direct OEM-specification replacement for the TE Connectivity 8-pin wire harness connector used on sunshade switch assemblies, automatic parking switch harnesses, and stop lamp switch circuits across Toyota and Lexus platforms. Cross-references TE Connectivity part numbers 1746875-1 and 1376368-1, and Toyota OEM number 90980-12558. Uses the 0.6mm contact series in white nylon housing — a non-waterproof interior connector for low-current switch signal circuits.
The 8-pin switch connector on Toyota and Lexus vehicles is used across multiple interior switch assemblies — sunshade motors, automatic parking systems, and brake light switches. These connectors are located in the dashboard, centre console, and brake pedal area, and are frequently damaged during interior trim removal or brake switch replacement. A damaged connector causes the affected switch to become inoperative, producing faults such as a non-functioning sunshade, automatic parking system errors, or a brake light that fails to illuminate — a roadworthiness violation.

Q: My Toyota Alphard sunshade stopped working after a trim panel removal — could it be the connector?
A: Yes. The 8-pin switch connector is the most common failure point during interior trim removal on Toyota and Lexus vehicles. The 0.6mm terminal is easily bent when the connector is pulled without pressing the release tab. Inspect the connector before replacing the sunshade motor or switch assembly.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
