What's the Word

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 bub, not an HID ballast.

Under Control: Morimoto makes it easy with the MotoControl 9004/9007 Bi-Xenon relay harness. Designed to be completely plug-n-play; it's a seamless solution to keep your low and high beams under control with the original stalk inside the car. Works perfectly with Bi-xenon projector retrofits and Hi/Lo HID systems.

Advanced: The third generation MotoControl 8-Pin Relay has a tiny built-in capacitor that stores and releases it's charge between mode changes. So even if there's a short gap between the low and high beam signals from your car, your HID's will run smoothly. It's sealed weather-pack connector is new for 2014 and is a major reliability upgrade compared to other bi-xenon harnesses.

Universal: This harness is designed to work with both positive and ground switched headlight circuits, making it universally compatible with all vehicles no matter new or old.

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). Its connections are explained in this video.

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 it's extruded aluminum relay shell that's been anodized and laser engraved - the MotoControl Harness will look factory fresh under the hood!

Focus: Since 2005, we have focused our efforts on lighting and that's it. Experience means we know the products. We know the technology. We know our competitors, and most importantly, we know our customers. We like to wrench. We like to drive, we like to ride, and like you: we demand the best for whatever it is that gets us going. That's why at LED Concepts; we only stock the shelves with today's best, brightest, and most badass LED Lighting upgrades.

Works but...

jesse cervene Reviewed: 04.26.2017

Harness came with 2 wires in wrong location. Had to swap the ground wire and low beam wire to make work properly. Otherwise its running now and works perfect!

Top notch service

My first faulty motocontrol box for a 01 mustang (9007) was quickly replaced by the excellent customer service. The only issue I had was figuring out the three signal wires from the box. Nonetheless, great quality product and very easy to install. Tip: ensure clean grounds and secure connections, and test headlight plug wires first to ensure proper install. Thanks a lot TRS!

Great Harness

Works flawlessly. only gripe is the lack of wiring diagrams for 9004 vs 9007. Had to re-pin the harness to the 9007 wiring. But the high beam circuit worked perfectly after i fixed the pins.

Awesome product

Ordered this harness for my Juke Nismo mini H1 retrofit. Had to change the pin configuration from 9004 to 9007. Works perfectly and made my install look very clean and professional, especially with braided sleeves on all the cables. No flickering when switching between low and high beam, capacitor does its job very well. Cable lengths were long enough for both sides. Can't complain about the pricing either. Shipping to Canada was reasonable and very fast. Thanks TRS!

easy install

First time dealing with TRS,and I must say after purchasing the 9007/9004 Morimoto MOTOCONTROL BIXENON harness along with 9006 Male Pigtail for my bixenon projectors, were both easy to hook up,& I'm thoroughly impressed with the build quality of these products!!,and after having some trouble with the wiring (on my part)a quick response from customer service with what I needed to know to finish the job right

Overall build quality looks...

Overall build quality looks good. Would recommend a cold weather rated insulation for wires. This is advertised as plug and play for 9004 and 9007 wiring. I found that NOT to be the case. I have 9007 wiring, I plugged it in to find that only the low beam was working. The high beam indicator on my dash was lighting up for both high and low beam. I measured the voltage at the 9006 plug going to the bi-xenon solenoid and it was -13v on both wires on one plug and +3v on the other plug.

Knowing that 9004 and 9007 plugs are the same except the ground and the low beam wire are switched, I swapped these two wires on the plug and then the high/low functionality worked perfect with battery voltage and ground at each 9006 plug and the dash high beam indicator then worked correctly.
