Toyota 100/105 Series & Prado 120 | 300 Series Steering Wheel Conversion Harness
Left stranded by a steering wheel supplier who didn't include the harness? You’ve just bought a premium 300 Series style steering wheel or upgrade Steering wheel for your 100/105 Land Cruiser or 120 Prado, only to realize the seller didn't provide the specialized wiring to make it work. This is the "Unicorn" harness you’ve been looking for.
⚠️ CRITICAL FITMENT CHECK – READ BEFORE BUYING
This harness uses a 12-Pin Plug configuration. Because we are likely the only retail supplier in Australia for this specific bridge, and to keep our stock available for those who need it, there are NO refunds or exchanges for incorrect ordering.
- Compatible: 12-Pin Factory Clock Spring
- NOT Compatible: 6-Pin Factory Clock Spring
- Check your clock spring pins against our photos before hitting 'Buy It Now'.
The Specialized Bridge for Older Toyotas
Unlike newer SUVs, the 100/105 and 120 Prado have a unique setup. Most "universal" harnesses simply won't talk to your clock spring. Our custom conversion harness bridges your aftermarket 300 Series style wheel directly to your factory 12-pin clock spring, including a dedicated sub-plug for your cruise control and full integration for your aftermarket stereo (TEYES, Android, Alpine, etc.).

Why Tuck’s Performance is Different:
- We Solve the "Missing Harness" Problem: We specialize in the parts that the big international wheel sellers "forget" to include.
- Real Australian Stock: Don't wait weeks for another "wrong" part from overseas. We ship daily from Queensland.
- Engineered for Conversions: Specifically designed for the 300 Series style wheel swap into 100, 105, and 120 series platforms.
🚫 FIRM NO REFUND / NO EXCHANGE POLICY
Due to the highly technical nature of this 12-pin conversion and the high demand for this exclusive part, we cannot offer returns for "change of mind" or "incorrect fitment." Please verify your factory clock spring is a 12-pin unit before purchasing.
Stop looking at a "dead" steering wheel. Get the only retail harness on the planet designed to get your 100/105 or 120 Prado upgrade finished today.
