i have a wiring harness for a 2008 chevy impala radio and there was a pin missing on the plug so im hoping maybe someone can tell me what the connector is called. there was a pin in a slot that wasnt used on my factory harness so i tried pulling it out to possibly re use it but the piece on the pin that keeps it held into the plastic connector broke off. i think the wire used is 20 gauge. i believe the connectors gm uses are made by delphi electronics. i appreciate any help thanks
