Curtis 1510-2501 to 1266-5201 Converter Harness

Curtis 1510-2501 to 1266-5201 Converter Harness – Plug & Play Adapter

Upgrade or replace your older Curtis 1510-series controller with a newer 1266-series unit without rewiring your entire vehicle.

This converter harness is designed to seamlessly adapt vehicles originally equipped with the Curtis 1510-2501 controller to work with the newer Curtis 1266-5201 controller. The two controllers use different connector styles and pin configurations, making direct replacement impossible without this adapter.

This harness handles all necessary signal translation, allowing for a true plug-and-play installation.

Key Features:

• Direct plug-and-play adapter – no cutting or splicing required
• Converts 1510-series wiring to 1266-series pinout
• Maintains proper operation of throttle, key switch, contactor, and control signals
• Clean installation – retains factory wiring integrity
• Ideal for controller upgrades or replacements

Why You Need This:
The Curtis 1266 controller is commonly used as a modern replacement for older 1510 units, but the connectors and internal pin assignments differ. This harness bridges that gap, allowing the newer controller to function correctly in vehicles originally wired for the older system.

Compatibility:

• Vehicles originally equipped with Curtis 1510-2501 controllers
• Designed for use with Curtis 1266-5201 controllers
• Common in golf carts and light electric vehicles

Important Notes:

• Controller may require programming to match original vehicle parameters
• Verify controller model and connector style before ordering
• This harness does not convert system voltage or change controller capabilities
