Well basically you cut the injector wires in half right? and now you hooked up the 4 wires to the wires that run to the injectors. So now you tie the other 4 that are connected to the butt end connector to the single wire left from the resistor box.

 

check out that site. connect it to that plug with the red dot. its a power distribution block.
