Well, i bought a 4 pin mic for my sons 6 pin Bearcat 880 on Ebay. I caught the error before it was shipped and emailed the guy to send a 6 pin. No reply and he went ahead and sent the 4 pin mic. I know there are adapters out there but I was wondering if any of you might have a clear diagram of how to modify the 4 pin to work as a 6 pin? As an example: pin 1 on the four pin connector is actually pin 3 on the 6 pin connector. I would like to give it a try before i spend another $12 on the adapter. Thanks!
