GrimmSpeed Wiring Harness for Hella Horns ( Part Number: 040005)
not enough 4 months ago
newb
it is a great product from grimmspeed but i would still highly recommend wiring up your relay with horns just this plug and play half of wiring will not be enough to keep horns going in longevity. as i am coming from experience and reading forums eventually your horns and or fuses will burn/ short circuit because the supertone horns require more power than the stock horns do.

QUESTIONS & ANSWERS

  • Q: Install  darthduck308 1 year ago

    I may just be having a brain lapse... but do I need to modify my stock wiring to install this, I see no wire to plug the power wire into... I have a short wire coming from my wiring harness to each of my horns.

      A:  You will not need to modify your wiring harness. These allow power to be pulled from your stock horn connector.

  • Q: Relays  angeloferradas258421 year ago

    Will this wiring allow for use of the relays that come with the horns?
    • 0 of 0 people found the following answer helpful

      A:  The harness does not utilize the relay that comes with the horns, you would need to modify the piece on your own in order to run the relay.
