This is a 12-inch, 1-to-1 cable adapter, perfect for bridging connections between two compatible devices or components. In a 1-to-1 configuration, each pin on Connector 1 connects directly to the corresponding pin on Connector 2—pin 1 goes to pin 1, pin 2 to pin 2, and so on.

This harness is a 1:1 adapter for a Molex 43640-0300 Micro-Fit 3.0 43640 Series to Molex 43640-0301 Micro-Fit 3.0 43640 Series. Please review the drawing diagram and BOM for additional details on the wire gauge and part numbers used in this assembly.
