capacitor, acap 7p

I just received my new audiobahn capacitor (ACAP7P).  I know how it is supposed to be wired (I.E. + wire from battery to capacitor, + out wire to amplifier, and have it grounded to the frame)  However, the ACAP7P says that it has its own power ditribution block.  From a top view it looks like  " J  L"  with each end of the letters being a spot where a wire inserts.  The plastic cover over it says "negative" at the top left terminal (IE. the top of the J) and "positive" over the top right terminal (IE. the top of the L).  Sorry that if that is confusing.  Anyways so my question is how do I use this as a power block.  To me it doesn't make sense that there would be 2 negative terminals. So I think one is a positive terminal, but then why would it be separated from the other positive terminals.  How can I connect this?  Thank you very much.  If more information is needed feel free to ask.  I am finding it hard to explain.

In this scenario the whole "J" is negative and the "L" is positive. It's not so much of a distribution block as it is an in line piece ie the positive comes from the battery and thru the cap and out to the amp, same with the negative from the frame thru the cap and to the amp. But you should definitely do a search on here for caps as most people will tell you for most people they are useless and are just a bandaid to cover a lacking charging system. Hope this helps.
