Our harness throughout the years has evolved into what we call, and are currently in the process of patenting, our Elite Series Harness. This option is an all-in-on solution for the ultimate DIY’er.. After 3 years, developing our own wire and combining LOC’s, processors, DSP’s and companies like Audio Control and Rockford Fosgate, who offer amplifiers with a high level input signal. By combining these top shelf solutions for the 12V market you can get an entire system upgrade at the same price of a factory head unit upgrade alone. This handcrafted harness is part of our original launch line, along with our Bose Harness and our Custom/Elevation/Work Truck Harness. Our line of harnesses are designed to keep your install quick, clean and simple, while retaining all the features in your vehicle like the Bluetooth, Steering Wheel Controls and OnStar.
LLJ Customs is the creator of the OEM Loopback Harness. When the company first began what is now known as the T-Harness and Loop Harness were not a definitive plug and play option available. What was typically found was wiring that needed modifications to the physical harness and add on’s that were not offered. Frustrated with the lack of options available, the extensive research needed and lack of help from audio shops we created something that would help others add new speakers, new amplifiers, new subwoofers and keep everything looking and functioning as factory.
The Loopback Harness comes with 2 ends, a signal side and a return side. The signal side will feed into a 4+ channel amp that takes a high level or a processor and returns (or loops back) that amplified signal directly from the output on the amp, to the speaker locations using the factory wiring. This is ideal if you are simply adding an amp to speakers or if you want to add multiple amps and go all out with a complete new system. Our harness grants you the access of your already available and paid for factory wiring.
The Loop Harness provides all of this in one consolidated product. It provides the signal, the return and it also provides power up to 10amps for most processor and DSP’s. This means you are only running 2 things, the Loop Harness from the source and the power wire from your battery. In some cars this is especially beneficial as sometimes they have the signal source (radio or factory amplifier) in the trunk along with the battery.
Want to add sub to car? Don’t want to tear into your wiring? Our Elite T-Harness is the answer. This harness was designed for the Non-Bose, Non-Factory Amplified system. You are able to build and customize your harness to your preferences and needs; like the length of the harness or adding an LOC unit of your choice. We offer a variety of choices like an Audio Control LC2i Pro, a Link2 or LinkDQ from Wavtech for when you are just adding a subwoofer/s. With an LOC added to the harness you are getting a full plug and play set up; with the harness providing signal and the LOC unit providing RCA out and remote turn on to your amp.
By providing customers the option to customize their harness we also provide the customer the option to use their own equipment. We want customers to be able to use the equipment and brands they are most comfortable with while being able to install their systems free of hassle. Every harness ordered without an LOC unit will come with a color card to help you wire your own equipment. The harness (with no unit) will come as a 4 channel, allowing you to use either a 2 channel, 4 channel or 6 channel DSP or processor.
The T-Harness is not limited to only adding subs/mono amp to your vehicle. You are also able to use this harness if you are planning on replacing your door speakers or installing full system and are planning on running your own wire back to the speakers. It can be purchased with a processor like an Audio Control LC7i or a Link6 from Wavtech, these are 6 channel processors. You also have the option of using a DSP like a DSR1 from Rockford Fosgate or a DM-608 from Audio Control. Just like a mono amp/subs install you are also able to customize the harness to just a 4 channel with wire ends only and use your own processor, DSP or amp that takes a high level (anything above 10V).
