DNA TOYSW04SL Starlink Toyota Square Factory Blank Switch 12VDC SPST Illuminated

Pop In. Wire Up. Factory Finish Square Socket Edition.

Product Overview

The DNA Automotive TOYSW04SL is a factory-fit SPST on/off switch designed to drop directly into the square blank switch socket found in compatible Toyota vehicles primarily the Prado 150 Series 2018-On and RAV4 2019-On, plus other Toyota models using the square switch format. Labelled "Starlink" to match the factory switch aesthetic, it replaces the square blanking insert with a functional 12VDC 3A switch with dual white LED illumination that lights up with the dash. No cutting, no drilling, no modification required.

At 22mm H × 22mm W × 52mm D, the TOYSW04SL is purpose-built for the square factory blank socket a different fitment to the round-socket TOYSW03SL. The six-pin wiring configuration covers positive input, positive output, illumination positive, illumination earth, and chassis earth providing clean control of a relay-triggered accessory circuit with a professional, OEM-matched result.

Features & Benefits

• Direct factory square blank socket fitment — Designed to replace the square blank insert in compatible Toyota switch panels without any modification. Pop the blank out, plug the switch in. Maintains the factory finish with a professional, OEM-matched result — no aftermarket look, no panel gaps.
• SPST on/off with positive switching — Rated at 12VDC 3A for positive switching circuits. Wire Pin 2 (Positive Output) to the trigger terminal of a relay to control high-draw accessories — LED light bars, compressors, auxiliary lighting, lockers — keeping the switch within its 3A rating. An inline fuse rated to a maximum of 3A is required on the positive input (Pin 5).
• Dual white LED illumination — Pin 6 connects to the vehicle's illumination positive, with Pin 1 providing the illumination earth return. The switch face lights up with the dash — consistent illumination alongside factory Toyota switches on night drives.
• Six-pin wiring — clean, logical layout — The TOYSW04SL uses a six-pin configuration (top to bottom): illumination earth, positive output, positive input, and illumination positive. Four active pins cover all functions; Pin 3 is unused. The wiring is straightforward and fully documented.
• Starlink-labelled switch face — The "Starlink" label matches Toyota's connected multimedia system naming convention, integrating naturally into the factory Toyota switch panel for a purpose-built, cohesive appearance.
• Square socket — different from the TOYSW03SL — The TOYSW04SL fits the square factory blank socket (22mm H × 22mm W) used in newer Toyota platforms including the Prado 150 Series 2018-On and RAV4 2019-On. The TOYSW03SL fits the older round socket (32mm H × 20mm W). Confirm your vehicle's blank socket shape before ordering.
• OEM-matched black housing — Black finish blends with Toyota factory interiors across all listed platforms for a clean, consistent switch panel appearance.

Frequently Asked Questions

What is the difference between the TOYSW04SL and the TOYSW03SL?

The TOYSW04SL fits the square factory blank socket (22mm H × 22mm W) used in newer Toyota vehicles including the Prado 150 2018-On and RAV4 2019-On. The TOYSW03SL fits the older round blank socket (32mm H × 20mm W). Confirm your socket shape before ordering.

Does this switch require cutting or drilling to install?

No. The TOYSW04SL pops directly into the square factory blank socket in compatible Toyota vehicles. Remove the existing blank insert and plug the switch in — no panel modification required.

Is a fuse required and where does it go?

Yes — a maximum 3A inline fuse is required on the positive input wire connected to Pin 5 (Red). Do not operate the switch without this fuse in line.

What is the maximum load I can switch directly through this switch?

The switch is rated at 12VDC 3A. For accessories drawing more than 3A, wire Pin 2 (Positive Output — Green) to the trigger of a relay rated for your accessory's current draw. The switch controls the relay, not the load.

Do both illumination wires need to be connected for the switch to light up?

Yes. The TOYSW04SL uses a two-wire illumination circuit — Pin 6 (Yellow) for illumination positive and Pin 1 (Black) for illumination earth. Both must be connected for the LED to illuminate. Connect Pin 6 to the vehicle illumination positive and Pin 1 to chassis earth.
