EAS HD Dice Stealth Antenna Help

[xnsf]

I just got the HD Dice Stealth Antenna (dual diversity version) and I have no idea how to install it. The instructions are different than the actual product.

So here's my dilemma:



The plugs for 1 and 2 don't seems to fit any other plugs. However, 1 and 2 can connect to each other



The instructions mention red dots and green dots, but I don't see any one the module. There are only two inputs, 3 and 4, which the BMW Antenna from the first pic does fit.



Here's the supplied cord, which is able to connect to 3 or 4, the HD Dice itself, and if I jam it, into the back of the Radio (5 below)



I don't understand how the wires connect because it seems like I'm missing something.

I tried BMW Antenna to Stealth, and then cable 6 to dice, but then my BMW radio will have 5 left over, and I have nowhere to connect the original HD antenna. 1 and 2 can't connect to anything other than themselves.

Thanks in advance for any help.
