help needed bad ASAP!

You don't need to "eliminate" the extra wire, as it simply won't hurt anything.

Here's a diagram of the 4 pin resistor, / 5 pin box. (I don't remember who originally posted this, but thanks)

Notice that in this diagram, the bottom of the resistor (ballast) has the "U" cutout, and that is the end that is jumpered together. It's blue because that is the traditional "ignition run" feed, which comes off the switch, through the bulkhead, and follow the blue----feeds the resistor, the regulator, alternator field, and power down to the ECU

Now the right side (top and bottom terminals) wiring is the coil resistor, and IS THE SAME for a 2 terminal resistor.

The only difference (4 pin) is that the LEFT side has the wire from the top left, down to the box. With a 4 pin box, this wiring simply doesn't do anything.

Of course with a 4 pin box, you can also just "plug in" a 2 terminal resistor.
