    New Fuel Pump, need wire harness?

    After installing the new parts on the sig below we found that my injectors are at full duty @ 5100 RPM. I am installing larger injectors and just for good measure I am replacing the fuel pump. After some research I believe the Racetronixs will work (as it can support up to 600 rwhp) I estimate no more than 420rwhp.

    The question is do I need to replace the wiring harness that they sell as an option?? Anybody have experience with this ??
