As far as I can tell, it should just plug right in. Any Motorola with the 8-pin modular jack should be wired the same. The only difference I know of is the behavior of the mic, ie, whether the tones are sent continuously as long as you hold the button, or just a short blip when you first hit it. There are also some programmable units with memories, etc. In fact, you can take a DTMF mic from, say, a Micor/Syntor and just change the cord and it should work too. I even took a Mostar DTMF mic and re-wired it for a EFJ challenger low band (7154 I think?). Just moved the wires around in the mic head! If you don't have A+ on the jack, though, yeah, it probably won't work... Jim
