Will the /6 ECU work with a V8?

So to switch from 4 prong ballast to 2 prong... this is it?

"On the first connector of the new ballast resistor, plug the terminal containing the 14 gauge brown wire onto one terminal of the new ballast resistor.
On the second connector, plug the terminal containing the 16 gauge dark blue wire onto the other terminal of the new ballast resistor. The unused
terminal on each connector will be left empty. As stated in step #5, they fed the fifth pin on the ECU and are not required on the new four pin ECU"

You just attach one brown wire, and one dark blue, and the other two just hang there??
Even if I'm still using the old 5 pin ECU for now?
