This is a touchy subject with some members. I only have my own personal and very biased opinion and really don't care to share in fear of reprocussion from one particular member. He'll be along shortly....I'm pretty sure.
The Racetronix bulkhead is an upgrade over stock. I had 2 factory ones fail. The Racetronix one is still going strong. Iirc the metal tabs where the wires connect on to are heavier duty.
