Looked to no end for the number of the pin connectors with no luck. But here's what I did the first time, removed the pins from the socket and cut them off. I do know they were at my Pep Boys Auto Store, Dorman, and I just matched them to the replacements in the store.
Final was the crimp them on the wire, 14ga upgrade 12 inch leads with ceramic sockets.
Now you could most likely just use the high heat or even standard sockets as I've have no problems after replacing the (correct term) pin female connector in the socket, pins are on the bulb.
Like I said, the pins are no difference looking, you have to take out the micrometers and them you see it. Plus in my search I read that the shock are tin, tin and the Dorman are copper, tin plated. Tin heats and weakens loosing its hold and arching, heat, heat and heat is the result.
Whatever the small differences my be it worked. I will continue to look for the part number, and if luckily will post it.
