Optimize Steering Wheel Controls with a Universal Wiring Harness

When drivers upgrade their car radios, they're often surprised to discover that their steering wheels’ audio control buttons no longer work. If your attempts to boost your radio's audio quality has left you with malfunctioning steering wheel controls, you may need a wiring harness. These devices are designed for steering wheel integration.

What is a steering wheel wiring harness?

Steering wheel wiring harnesses are adapters that connect original steering wheel control buttons to upgraded radio receivers. By using one of these adapters, a driver can retain the original use of his or her steering wheel's audio buttons, like Resume, Set, and Volume. When a steering wheel wiring harness is labeled "universal," it means that it can be used with any make or model of car.

What features do wire harnesses typically have?

Each wire harness is different, but common features may include:

  • Button multiplexing: Some universal wiring harnesses have a button multiplexing feature, which means that each button on the steering wheel can be programmed to serve more than one function. When drivers use this feature, pressing the button will do one thing, like increase the volume, and holding the button down will do a separate thing, such as skip to the next song.
  • Auto-programming: Many harness options can automatically detect the original functions of the steering wheel buttons.
  • Online programming: With some harness devices, the steering wheel controls can be programmed and changed online or via an app.
What are analog and digital signals?

When selecting the right wire harness for your vehicle, you need to know whether your car uses digital or analog signals. Some cars may use digital signals to connect the radio and the steering wheel controls whereas other cars may connect the two components via analog signals. Some wiring harness devices read analog signals, others read digital, and a few are equipped to read both.

What are the main components of wiring harness devices?

When you open the box of your new wiring harness, you'll likely see the following:

  • Steering wheel control interface module: The main component of the harness, this module will come attached to wiring and cables. The cables may terminate in connectors.
  • Wiring harness: The wire harness itself is comprised of multiple wire that are installed in the radio.
  • Resistors: Most wire harness systems include several resistors of varying levels of ohms.
Can you install a universal wiring harness?

If you have experience installing car components, connecting a wire harness to your car radio may be possible. During the installation process, you will have to identify the correct wires in the radio, and then connect the wiring of the harness to the identified radio wires. For the most secure installation, you may have to solder the wiring together. Drivers who don't want to install their universal wiring harness can have it done by a professional mechanic.
