What is the MECP recommended practice for installing data wires in an alarm/remote start data interface?

The recommended practice for installing data wires in an alarm or remote start data interface emphasizes using T-taps or non-permanent connections. This method allows for easy disconnection and reconnection, which is crucial for troubleshooting, modification, or repairs in the future. T-taps provide a reliable yet reversible method of connecting wires without damaging the original wire's integrity, which is particularly important in a vehicle's electrical system that may need adjustments over time.

Utilizing non-permanent connections means that should there be a need to change or upgrade components, the technician can do so without extensive rewiring, which maintains the integrity of the vehicle’s harness and ensures continuity in functionality. This practice also aligns with industry standards that prioritize not only reliability but also future serviceability.
