Replacement expansion board for 1/14 RC cars — a passive shunt extender for the 2-way rotating light interface that can also be used to extend the steering gear connection. Key benefits - Simplifies wiring: lets you split or extend a single 2-way rotating light interface to feed multiple lights or route connections without cutting or splicing wires. - Saves time on repairs and upgrades: a direct replacement accessory for common 1/14 RC car installations when an existing board or connector is damaged or when adding accessories. - Keeps installations neat and reliable: provides a dedicated extension point to organize accessory wiring and reduce strain on original connectors. Main features - Function: Extends the 2-way rotating light interface; can also be used to extend the steering gear connection. The board is a passive shunt/extension only. - Compatibility: Designed for use with 1/14 RC cars and accessories that use the same 2-way rotating light / steering gear connector standard. - Control behavior: This expansion board has no control function — it only splits or extends signals and power between connectors (shunt extension). - Form and fit: Intended to match standard connector layouts for 1/14 models so it integrates with existing wiring harnesses and accessory modules. Practical use scenarios 1) Add a second rotating light to a 1/14 RC truck: split the original 2-way rotating light feed to power two lamps while leaving existing controls unchanged. 2) Replace or extend a steering gear connection during maintenance: move the steering servo wire run or replace a worn connector without rewiring the entire harness. 3) Centralize accessory wiring on custom builds: use the board as a simple junction to route light and servo lines neatly into a control area or chassis bay. Installation and notes - Passive component only: does not provide any signal switching, PWM control, or logic — it simply joins wires as a shunt extension. - Verify connector compatibility and pinout on your specific 1/14 model before installation to ensure correct wiring. - Use as a replacement or accessory when you need a straightforward, low-risk way to extend or split the 2-way rotating light interface or steering gear connection.
