Thread: Sniper Main Wiring Harness

  1. #1

    Default Sniper Main Wiring Harness

    Just curious as to why the positive lead size is 12 gauge and the negative lead is 14 gauge? I've been taught the positive & negative wire size should match.

    Also, why MUST the positive & negative leads go directly to the battery? Holley Tech's answer is to mitigate voltage flyback & RFI.

    The videos are interesting and not something I didn't know. However, the electronics today are pretty tough compared to 30 years ago where conditioned power & isolated grounds were recommended for simple personal computers. If the Holley engineers didn't build in the necessary protection to prevent harm to the ECU and mitigate RFI by using the proper shielding, then shame on them!

    Thanks for all your help; I've read every thread on this forum and you are definitely an asset to the community.
