W126 headlamp plug pin part number help

Does anyone know if you can buy the pins inside the plug that connects to the headlamp housing?

This is a female plug that connects to the headlamp housing. Inside the headlamp housing there is wiring for all the various bulbs etc.

I am about to wire in some relays and would like to do this properly by opening the plug up and using new pins so that it all looks factory rather than cutting the existing wiring.

Thanks in advance.

Matt.
