Thread: EFI & Nitrous Solenoids

    2 or 4 AWG would be for the battery's ground in the trunk to the engine block if I'm watching the video correctly. What would you use for the power & ground wires on the Sniper unit to go from the intake to the battery in the trunk? 10 AWG? I bought my kit used and those wires were already shortened so I have to lengthen them. I really appreciate the help!

    If lengthening the EFI main power & ground wires to the rear trunk battery, then increase one size larger AWG.
    So yes, 10 AWG: https://www.holley.com/products/fuel.../parts/558-490 (Holley Sniper EFI Main Harness Wire Gauge List)

    Thank you again Danny. I sincerely appreciate the help being an EFI newbie.

    On the battery grounds I'm going to run a 2 AWG welding cable from the negative terminal to the engine block. I already have a 4 AWG welding cable from the negative on the battery to the frame and also from the engine to the frame. So I just need to go from the battery negative to the body? And with at least an 8 AWG wire? Since my battery is in the trunk could I just go to the trunk floor?

    Yes, that sounds correct to me.

    Yup, sounds good to me also. I agree that you should bump up the wire size on the Sniper wires to the next gauge heavier for the long distance from the Sniper to the trunk mounted battery. I did that and I'm happy I did. I have zero RFI or power/ground issues. I did the same thing with my HyperSpark power/ground also.
