this radio is made by PEIRCE SIMPSON and is wired like a cobra.
pin 1 shiels or ground
pin 2 is audio
pin 3 is transmit
pin 4 is recieve
shield is a bare wire wraped around the audio wire.i dont know the colors of the wires in the echo mic.the transmit wire will have contiuity with the shield wire when the mic is keyed that wiregoes to pin 3 . there should be 2 wires left. check these wires one at a time with the shield wire one will have contiunity . this wire will go to pin 4 recieve.the other wire will go with the shield wire on pin 1
this is the way you find how it wires. it will take an ohm meter to find whice wire goes where.

I suggest buying a 5 pin to 4 pin adapter. Ebay has them for $6. I would go chopping wires on the mic. Cobra 29 ltd is a nice radio. Have one myself.
