OK that doesn't even make sense to me and I've done it.

Simple-

1.open up wire loom
2.find the thicker wire coming from each injector (yellow I think)
3. cut the 4 thick injector wires
4. wire the 4 black wires from the irp to each cut yellow wire running to each injector
5. The white wire attaches to ONE thick yellow wires (that you cut) running back to the ecu
6. the remaining 3 yellow thick wires get taped up and are not used

if you can't understand that email me and I'll make a detailed diagram
