Does a cable like this exist? I have a Shure 183 lapel mic with Mini XLR male plug that was used on a wireless body pack. I'd like to use to to do voice for video either plugged directly into my camera or a recorder for later syncing. Could I chop it and terminate it into a normal mini plug? How would I know which wire goes where if I did that. I looked inside the plug and it has the normal red, black, and ground wire. Is red and black for right and left or positive and negative?
