Cotether 36V 350A ITS Speed Controller for EZGO Medalist & TXT (1994–2019) | 5-Pin, 3-Big-Blades | 1206 Series

Cotether ITS Speed Controller for EZGO Medalist & TXT (36V, 350A)

Upgrade your EZGO Medalist or TXT electric golf cart with Cotether’s ITS motor speed controller. Built for 36V systems, this unit delivers robust current handling and precise throttle response to support smooth acceleration and steady power delivery. It’s designed to work within the Medalist (MED) and TXT families from 1994 through 2019, giving you a practical path to modernizing an aging control system without overhauling other electronics.

The controller is configured for a 5-pin connector and uses a 3-big-blade setup, aligning with the original wiring topology and motor interface. This combination helps maintain a clean installation and preserves the intended throttle feel for everyday driving, from quick starts on the first hole to steady cruising on the back nine.

Compatibility, parts, and installation considerations

• Compatibility: EZGO Medalist (MED) and TXT models dated 1994–2019, featuring ITS throttle input and Series Motor configuration.
• Part numbers: Replaces multiple references such as 1206-4301, 25864‑G03 through 25864‑G09, and related codes; verify your exact part number before ordering.
• Connector and pins: This unit uses a 5-pin connector, not a 9-pin interface; confirm your cart harness matches to avoid installation issues.

• Important limitations: Not compatible with DCS or PDS systems, and not a Separately Excited (Sep Ex) motor controller; ensure your motor type aligns with the Series configuration.
• Installation guidance: Check vehicle model, confirm the part number, and review wiring diagrams or tutorials to align with the 5-pin connector and 3-big-blade design.

Real-world benefits and use cases

This controller aims to provide reliable throttle control and consistent performance across a range of operating conditions. Potential advantages include more predictable response at the pedal, smoother power delivery during transitions, and a compact, purpose-built solution for EZGO carts in the Medalist and TXT lines.

Use it as part of a planned upgrade cycle for an aging cart, a preventative maintenance step, or a mid-life refresh to extend service life without a full electrical overhaul. While results vary by cart configuration and battery health, many users report improved drive feel and steadier performance with appropriate matching of components.

Before purchasing, review your vehicle’s model year, confirm the compatible part numbers, and ensure that the wiring harness and connector type align with the 5-pin 1206-series design. This careful check helps you achieve a smoother installation and a more dependable drive experience.
