This Standard 4-PIN Round Transmitter from TowMate is used on TowMate Tow Lights that do not use an external antenna. This transmitter does not have an antenna and the electronics are injection molded to ensure that it will resist the elements. If you are purchasing a transmitter for an existing light, you will want to match the wire colors of the transmitter and receiver. A red wire indicates the newest and most current series of electronics & will work with the I-MON monitor; a green wire indicates an older style prior to the series of electronics (Doesn't work with I-MON). Please check your wire, and choose your color before ordering. Not sure which transmitter you need give one of our Customer Services Reps a call @ (800) 222-6047 and they will be able to get you what you need.

• Choose from two wire colors: Red, Green
