help with battery relocation attempt

I am going to relocate my battery into the trunk and need help with some wires and what to do with them....

From stock there is one small wire that goes from the mopar regulater box next to the battery and hooks up the the battery, and the main + power cable goes from the bat to the starter with two connections. how dp these wires get connected and where when there is only one + wire going from the trunk to the battery.

I noticed in another thread I could jump from one terminal to the other on the starter if so then what do I do with thhe regulater box wire....... Thanks for your help
