1) The specified polarity is based on the motor connections for travel direction 1 (forwards) with respect to NEM 631.

2) Contact 3 can remain unconnected or be used for an additional function. Any manufacturer assignments should always be documented. If a special function is assigned, it is critical that short circuit protection (protection diode) be installed to guard against damage in case of reversed polarity.

3) Rectangular cross section pins are an alternative so far as they meet the same load capacity and physical contact quality as round versions.

4) The specified load applies to each individual pin; it is not tied to decoder, motor, lighting nor additional component load capacity. Because many decoder manufacturers provide lower capacity light and function connections, it is recommended that vehicle manufacturers document how much current headlights and additional functions draw.
