You should punctuate your sentences, that whole glob was a pain to read. Did you just try google'ing it?

For obd1 you take all the wires that run to the resistor box and wire them together. Should be the 4 wires from the injectors and the the 2 wires from the old dual point injectors that they tell you to wire together and run to the resistor box. It will be the 2 yellow and black wires from the old injectors that run to the resistor box and the 4 red and black wires from the new injectors.
