What Is A Harness Kit?

Every car has its own wiring system set up from the factory to run the electronics in the vehicle. Aftermarket wiring harnesses can help you connect your new car stereo easily and effortlessly. There are different types of aftermarket wiring harness kits that exist today, however most are pretty basic. The basic wiring harness is the most common and provides basic connectivity for both the speaker wires and the power/ground connections.

Many of the older cars will allow you to use an aftermarket harness to make basic connections behind the radio; but the newer cars are much more advanced and utilize many different modules to run the infotainment system. A common example of today’s newer vehicles electronics is when the stereo system has an amplifier, a display screen, radio control panel (or button pad) and radio tuner that is all located in different areas of the vehicle. What you see where the radio information displays in the car is really just a display screen showing information that the radio tuner is sending to it. In these cases; a specialized wiring harness is needed, with all the proper connections and terminals to allow all the components to talk to one another without setting any error codes.

I can’t say enough nice things about these guys. First of all GREAT product. More important to me is the customer service they provide. Anthony is very knowledgeable and passionate about his work. He was able to get me set up quickly and with the information for me to confidently do the work myself. Again, thank you MVI for your help and commitment to excellent customer service.

The team at MVI was great! They helped me upgrade my 2015 Silverado to factory navigation with Apple Carplay. The parts were nationally back ordered when I ordered, but they arrived earlier than the date MVI said they would ship. I was a little nervous about having to take a few things apart to install the parts, but the instructions and video links made the installation very easy with no issues. They send you a video after you finalize your purchase showing the installation and what tools you will need. I spent $12-$15 on amazon for a pick tool set and a plastic dash pulling tool set and things went very well! I truly have no complaints! I highly recommend MVI!

Hands down the best aftermarket interface products for av integration out there. I leveraged unlock and DVD upgrade, but to keep the truck together Anthony preprogrammed the Hmi and the screen and sent requesting my cores back. Truck was literally apart for 40 minutes under diy install. If you need anything av, start at mvi inc.
