How to disconnect most electrical connectors

Mark Booth put together a helpful explanation for someone wanting to know how to disconnect the locking wiring connector underneath their seat, and I thought I would repeat an edited version of it here to help others in general.  These locking connectors are not unique to vehicles produced by Mazda, but rather are currently typical within the automotive industry.

  • Pull lock (#1; usually a contrasting color like white or yellow) partially out (should notice a detent*)
  • Depress tab (#2) and hold it down…
  • While pulling the connector (#3) away from it’s mating connector

BE SURE TO DISCONNECT THE NEGATIVE BATTERY CABLE FIRST and depress the brake pedal to discharge the circuits.  This will help insure that the electronic modules will recognize all connected devices upon re-connection.

*    For instance, in order to change the oil filter, a similar connector at the turbo diverter valve needs to be disconnected to get it’s harness out of the way, but if you are too aggressive with the yellow lock, it will inevitably separate from the connector and fall into the bottom of the engine compartment, and the belly pan may make it very difficult to retrieve.

⇓  This photo shows the unlocked connector ready to pull away from it’s mating connector on the diverter valve.
