Its really easy to do since the radio he is just for show locate the pin for the mike switch
and the end of the mike cord you can see where it plugs in on the radio head by taking the cover off the back of the radio head Apply power source to that pin and to the positive side of the transmit light you will need to ground the negative side of the transmit light too the same goes for the green light on the radio head it is easier to wire since you don't have to find the pin for the mike. Hope this helps
