I am running wires into the door, I have the door wiring harness disconnected
at the body and can't help but think that if I could get a hold of those pins Nissan used, I could add my wiring without compromising the ability to disconnect this wire harness from the body.

Anyone know where to get them of any reseller here carries them?

 

Anyone know what this type of connector is called?

 

umm molex pins?

 

You could try to find the actual molex/harness online somewhere, and then just scavenge the pins from that. It sounds great in theory, but I wouldn't leave those connections to chance. Just drill (carefully!) through your molex and run the new speaker wire, and call it quits

 

Yea, thats what I did but i would have preferred retaining the OEM function.

I will still look for those pins, I can always redo it in an area where I did not drill the hole.
