I need a wiring diagram for the courier Centurion cb mic, it has a phono jack pin tip .

look up microphone wiring diagram for your cb and mic. more than one way to wire, depending on mic and cb having 4 or 5 on plug end. write down mic numbers and cb plug numbers. if audio on mic is 3 and cb is 4 put 3 on 4 pin check each wire. using power mic make sure red and black wire are on the right pin, can damage radio or mic or both.

With the CB radio off & not connected to power, check or have a friend check the contact points, at each end with a Volt/Ohm Meter.

the best i can find is this
red pin 5 ptt
black pin 4 ptt ground
white pin 1 mic
shield pin 2 mic ground
no connection pic 3

first you need to know if its compatible, most are, but not all,
Astatic mics are basically a 6 wire mic/yellow is not used most of the time. second,find the wiring code for your radio then you have to match the color code to the mic, you can do all of this by searching online.

• Hi, I can help.

• The Diesel Electronics CB will work but you have to wire it as stated below.

1. #1 Shield and Black - Ground
2. #2 Yellow - Audio
3. #3 White - Transmit
4. #4 Red - Receive

• I don't know if anyone before you has re-pined that mic or not so if you just remove that little Philips screw at the mic connector and then give it a quarter turn you can slide the connector out and take a look and compare the wiring. The actual numbering for the pins on the Galaxy 4 pin mic connector is as indicated below in the diagram. As you look at the mic tip make sure the indent on the mic is as it is the diagram.

• If you have any comments please feel free to leave them here.
• Hope this helps and thank you for using FixYa.

I would suggest shipping the unit in with the mic and let me do it for you. www.dodgem250.com

Does the roger beep come with instructions? It can vary between beep boards.

Typically it gets installed inline with the mic jack.

There is a wire or pin on the board where the tx wire, and the rx wires go.These wires get disconnected from the mic jack, then a wire goes to the tx pin. Then there is an audio wire that gets connected to the audio wire of the mic jack. Then the black wire to ground, and the red wire to switched 12v right off the power switch.

Here is a schematic of the board connected to the mic jack so you know what pin is what.

Again, I would need to know what roger beep board you would like to install.
