I am looking where you can purchase the wiring harness pins for a Chevrolet 2004 Silverado. On my drivers side seat at the air bag wiring harness connector - the pin for the green wire on the harness broke in half and now service airbag light is on. I believe it's called a data link connector pin. I've been to autozone, radio shack , etc... can't find it anywhere. Any ideas?

Pin has number P04 on it.
