TowMate TM5004-G is a rugged, weather-ready 4-pin round transmitter designed for TowMate Tow Lights that don’t require an external antenna, delivering reliable remote control for your trailer setup.

This green-wire variant is part of TowMate’s standard 4- or 7-pin round transmitter lineup, built with an injection-molded enclosure to resist the elements and keep signaling reliable in harsh conditions. When paired with the matching receiver, it provides dependable remote control for your trailer lighting system.

Why this matters

• Durable, weather-ready design: injection-molded electronics and housing seal out moisture, dirt, and road grime so signals stay strong in outdoor towing environments.
• No external antenna: simplifies installation and reduces the risk of damage from road debris or tight spaces.
• 4- or 7-pin round compatibility: versatile support across a broad range of TowMate lights, making it an easy replacement or upgrade for aging systems.
• Color-coded electronics: green wire indicates an older electronics series and does not work with I-MON monitors; red wire indicates newer electronics and is compatible with I-MON. If you’re replacing a transmitter, match the wire color on both transmitter and receiver to ensure proper operation.
• Reliable pairing: engineered to work seamlessly with the corresponding TowMate receiver for consistent remote control of your trailer signals.

Who it’s for

Ideal for technicians upgrading aging TowMate lights, fleets seeking dependable, low-maintenance remote control, RVers, and DIY trailer enthusiasts who value straightforward compatibility and durable performance—especially when upgrading older electronics that don’t support I-MON.

Use cases and practical tips

• Use as a direct replacement transmitter in existing TowMate setups to extend the life of your lighting system without changing other hardware.
• Choose this green-wire TM5004-G if your system uses older electronics and you don’t require I-MON monitoring.
• When planning an upgrade across multiple trailers, verify wire color compatibility on both transmitter and receiver before ordering to ensure smooth operation.

Decision tip: Always verify that the transmitter and receiver share the same wire color to avoid compatibility issues and ensure reliable signaling.

The TM5004-G offers a practical, reliable solution for fleets, RVers, and DIY tow projects where quick swaps and durable performance matter—especially when upgrading older electronics that don’t support I-MON.
