2 issues.  First, I plugged in the stock/factory tuner cable from the 7200 to my IC-4h tuner, but now I can't get it out and I'm afraid of forcing it.  Is there a release I can't see under the boot, more force or am I being dumb?  I'm afraid of breaking my new radio.
Second, what is the name of this tuner connector/plug and where can I buy another?  I want to have a permanently installed line out to a tree behind my house where the IC-4H will live most of the time, which will need a longer control/power cable than the stock.  I'd like to keep the stock cable as-is for portable/camping use.

I will also need additional power connectors, but I know how to get those.  I've looked around and can't seem to find the tuner connector or how to release it.  I figure it would be faster to just ask here.

That tuner connector is a Molex.  I bought them locally.  

I had found pkgs of Molex 1490PRT, which contain 2 plugs 03-09-2041, 2 recepticals 03-09-1041, and 10 pc each male and female .093" pins. These mate up to the LDG
tuner's cable and the socket on the back of the IC-7200 (and other Icoms).  I used these to make an extension cable for my LDG tuner.

http://www.qsradio.com/Rotor%20and%20Tuner%20Cables.htm  Has the plugs, sockets, and 4-wire cable.

They also have on that page 50' and 100' tuner cables already made up.


They can be difficult to remove.  Just keep working them.
