red wire to on/off control of the radio (12 volts )
black wire to ground pin of the mic jack
white wire to audio pin of mic jack
you have two wires going to the button (orange and blue) on the unit one of those wires will go to the ptt pin (transmit) of the mic jack (the other wire is just a ground wire that you won't need to use) so it's one of the two wires is all you will need , as long as you have neg and pos and audio wires correctly you can just try either orange or blue wires to the transmit pin of the radio on the mic jack ........once you figure out which of the two wires you will use (it will only be 1 of the 2 ) you are set to go dude !! your noise toy will then go off every time you key your mic . .........No offence here but I can't stand those types of noises everytime I key up !! ......because once you wire it that way , it will always go off when you DK the radio , So you think the button feature sucks ??? well , at least it gives you the option of not having to use the nerve racking thing 24/7 when your trying to have a conversation with somebody , they do get annoying after a while for the other guy. Don't mind me much dude , I just have never been a fan of the Tram sound or Rodger beeps for that matter !! anyway ...that's all there is to it dude !! it's just either the orange or blue wire that goes to the transmit (ptt) pin on the mic jack. Good luck to you sir.
