These three-way Y-style cords will allow you to connect a two-way radio to your iMC headset.
CBL100-MDIN The portion of the cable that connects to the standard 3.5mm stereo mini-plug on your radio is 6 inches long and the other two lengths of the cable are more than 36 inches long. One of those ends in a mini-DIN plug for connecting to an iMC headset that uses that type of connector. The remaining length of cable will connect to a push-to-talk (PTT) button (sold separately).
CBL100-MIT A replacement cable for the one found in the iMC MIT10 Multi-Control Kit, this item connects a two-way radio to the control box. A 3.5mm socket splits into two 30-inch long cables, one of which ends in a push-to-talk (PTT) button with a hook-and-loop style wrap to attach it to your handlebars; the other cable ends in a 3.5mm audio plug. Also includes a 12-inch Y-style adapter with a 3.5mm socket that splits into dual 3.5mm plugs.
