Is MECP's recommended practice for connecting a steering wheel control interface to use T-taps or 3M Scotch Locks?

The recommended practice by MECP for connecting a steering wheel control interface is not to use T-taps or 3M Scotch Locks. These methods can compromise the integrity of electrical connections in a vehicle, leading to issues such as poor or intermittent performance of the steering wheel controls. Instead, MECP emphasizes using solder or other more reliable connection methods, as these provide a stronger, more secure, and less error-prone way of connecting wires.

Using a soldered connection ensures that there is a solid electrical joint that minimizes resistance and potential failure points. Additionally, proper connections help maintain the vehicle's original wiring integrity and can prevent long-term damage that might occur from the use of quick tap connectors that could corrode or loosen over time. This practice reflects the industry's best standards for audio installation and contributes to a better overall performance and reliability of the steering wheel control functions.
