Frequently Asked Questions

Is This Switch Compatible With Manual Transmission Vehicles?

Yes. He notes compatibility concerns: the SLS159T fits many vehicle-specific applications, including manual transmissions when matched by part number. Installation tips: verify OEM part number, confirm correct push-button travel and connector clamp alignment before fitting.

Can I Install It Without Removing the Brake Pedal Assembly?

Yes. He notes brake switch installation typically proceeds without removing the brake pedal assembly; minor pedal assembly modifications or alignment checks may be required, but full removal is generally unnecessary for this vehicle-specific replacement.

Does It Include Mounting Hardware or Screws?

No; it does not include mounting hardware or screws. The responder notes mounting options are limited to vehicle-specific clamps and ring controller fittings; installation tips recommend verifying clamp compatibility, preparing correct fasteners, and testing switch engagement.

Is the Connector Color Standardized Across Models?

No — the connector color is not standardized across models. The response notes connector compatibility depends on vehicle application; color variations reflect manufacturer batches and OEM specifications, so fitment should be verified by part number and wiring, not color.

Can It Trigger Trailer Brake Lights as Well?

Yes; the switch can trigger trailer brake light activation if wired into the vehicle’s brake circuit and trailer connector. The device’s normally-open contact and 12V operation support trailer brake light activation when properly integrated.
