Reality Check: Customers often ask, Do I really need a harness? Yes! A relay harness is designed to deliver steady voltage to your HID ballasts directly from the car battery. Nobody likes a flickering headlight, so why risk it? Factory headlight outputs are really only designed to power a halogen light bulb, not an HID ballast.
Don’t Skimp: As one of the most important parts in any HID lighting upgrade; don’t skimp out when it comes to your wiring. It doesn’t matter how good your ballasts are. how good your bulbs are. If your harness is a piece of crap: when it gives out your headlights are gonezo. The Morimoto HD Relay harness is easily worth the premium price compared to cheaper alternatives.
Plug n Play: The layout of the harness makes it easy to install. With just a few simple connections, even your mom could set this thing up! Wire lengths are long enough to be used in everything from compact cars to SUVs and it’s designed to be 100% plug and play (no cutting or splicing needed).
Compatible: The HD relay can be used for low beams, high beams, or fog lights on most vehicles. The harness uses industry-standard outputs for compatibility with 99% of ballasts out there, and all of the ones we offer here at our shop. Note, if your vehicle has a can-bus system or a finicky pulsed headlight circuit – check out the Standalone Canbus or Mopar Spec harnesses from Morimoto
Fail-Safe: Unlike most generic harnesses out there that rely on a single low-quality relay to power both headlights, the Morimoto Harness utilizes one relay per side- so if one did happen fail, you wouldn’t be left completely in the dark. Each 40A relay is completely sealed against the elements using ribbed silicone upper and lower seals, and has an flywheel diode for back-EMF protection. Every other connection harness-wide is sealed with the proper silicone grommets. Live somewhere with weather that regularly sucks? No problem.
OEM Grade: Aside from being ahead of the game from a technical standpoint, the HD relay is also a work of art. With it’s wiring protected by abrasion-resistant Techflex mesh sleeving and OEM-style relay cubes held together by a mounting bracket cut from polished stainless – the HD relay will look factory fresh under the hood!
