Where does this go?

[brainbug007]

Ok think i've got you now, so all I'm really doing is adding a new wire between the 6 pin plug and the 4 pin plug at the battery? What's the best way to do this? Do I try and strip down part of the wires and then solder on? Is there something like a 3 way terminal block I should use? Or is there a way to open the 4/6 pin plugs up and insert the wire down into them?
