Lookiing for the mic wiring diagram with color coded wires for my Pace CB 143 mobile cb radio, it's in Sams PhotoFacts CB Volume 79, which I'm missing. Any help would be much appreciated... Beachcomber
Thank you for the info Greg, its not hardwired, theres definitely a 6 pin din socket on the radio1 = Black
2 = Shield and Red
3 = N/C
4 = W ( audio)
You're right about that. I use my flourescent lamp with a magnifier built-in to see the numbers and draw a pic as to what each pin is numbered. Works for me...Tricky part is to sufficiently magnify and make out the molded-in pin numbers on the inside of the plug's black insulator body.

Worse comes to worse I can open the radio up and look at the wires on socket.You're right about that. I use my flourescent lamp with a magnifier built-in to see the numbers and draw a pic as to what each pin is numbered. Works for me...
Thank you TM86, thats exactly what I needed. And yes, I can believe Sams, a pic of the 6 pin din socket on the radio:I just happen to have CB-79. Although someone once tore the schematic page in half and failed to put it back together properly. It shows a 6 Pin DIN connector for the mic. If you can believe Sam's:
Pin 1 - TX
Pin 2 - Shield/ground (2 wires)
Pin 3 - NC
Pin 4 - Audio
Pin 5 - NC
Pin 6 - NC
The PTT switch connects the mic hot side to pin 1 and shorts pin 2 and pin 4 together.
