Which identification should I match?

Compare 1604KL-04W-B49 M51 character by character, then check the mounting and actual connector. Similar base codes do not establish interchangeability.

Do the visible leads prove a signal function?

No. Lead count and plug appearance do not identify PWM, tachometer or alarm functions. Confirm the pinout before connection.

Exact-version dimensions and performance remain unconfirmed. Product photograph; photo support; quantity quote.
