Midland to Cobra - CB Radio Mic Re Wiring 

DIN or that other design?

@@buckfiden9106 Doesn't matter anymore, thanks. I picked up a new Cobra mic. Thanks.

I don't know about that exact model of radio, but generally the 4 wires on a Cobra mic are: - Ground/shield - Audio (Your voice) - RX/Audio out (Speaker output is routed through the mic on Cobra radios, so you'll get no audio out without a mic) - PTT (What activates the microphone) You can poke around to figure out which ones are which with a pair of tweezers. You might be able to open it up and see which pin is the ground, and then just short the ground pin to each of the 3 other pins until it either keys up or your audio comes in, and that'll tell you which of those pins do those jobs, and the only remaining pin that doesn't do something obvious has to be your audio input. I've got an image I found on the internet somewhere years ago that has the following layout for a Midland 4 pin, which looks like you basically just swap 1 and 2 and swap 3 and 4 with one another relative to a Cobra 4 pin. I'll post a link to the image shared from my Nextcloud server if RU-vid doesn't snip out the link. The link will expire in 30 days. 1 - Audio 2 - Shield-Com 3 - RX 4 - TX marcusandash.net/index.php/s/85P3GcmCtyJqMEy
