Okay I konw that I have to delete the resistor box.

What wires need to be cut spliced etc?

For high-impedance injectors, there should be one ylw/blk wire for each injector that supplies switched 12VDC+. All of these will be connected to the resistor box so you'll need to find a way to route 1 wire to each of the injectors.

The injectors will also have a second wire that are pinned individually to 4 separate pins at the ECU. The ECU grounds each one separately to fire. Each GND wire at the injector will be a different color. Don't mess with any of those wires when wiring. Polarity doesn't matter, but it helps to keep the wire colors consistent.
