The connector for the ground bypass next to the antenna wire does NOT have a metal tang that would connect to the radio to effectively ground that pin.
Yes, That is correct, there is no female slot when it goes into the radio, it is only plastic. if you are looking at the top of the connector the connection band stops at the last 4 pins.
It is the one that IS posted above, only thing is the metal band with the tabs connection stops at the last 4 pins,
I don't mean to be a smart ass, but I'm having a lot of trouble visualizing what you are seeing from these descriptions.
It should look like that connector, only with that wire on the bottom right not there. There should be 4 holes, not the 3 pictured. The only "metal" in that connector is the terminals crimped on the end of each wire and then inserted into each hole. Things like "the connection band" have me confused. I'm not trying to make fun of you because I sometimes have the descriptive powers of a 4 year old (lots of "thingies" and "whatch-a-macallits"). A picture would help.
I am going to try and just solder the tip in a "y" fashion or something to act as a receiver for the radio pin,.....any other suggestions, please post, this might be new for the Z2's as well
I would highly suggest taking a picture of what you are seeing and post it, if you can't post it you can email me a copy of it at one of my emails here: http://www.sminntech.com/contact.html and I will post a pic so people can see it. But if they changed something we would like to see what is up. I know if there is something different people are going to start asking me for information that's for sure.
