4-Pin Molex Connector - Connection Tips

Important: The 4-pin ATX peripheral (Molex) connector is a legacy design with looser manufacturing tolerances that can make connections challenging.

Why connections can be difficult:

Older connector design with wider pin tolerance ranges
Sleeving and heatshrink near the connector can create tension on the pins

Connection tips:

Twist the wire bundle gently behind the connector housing to relieve tension
Visually inspect pin alignment before attempting connection
Apply gentle, even pressure - forcing the connection can push pins out of position
If resistance is felt, stop and check alignment rather than forcing
