More to the point, anyone know the name of it?
I pulled the IP pump on my currently dead SDL and with this fitting, I first popped off a little cap thingy. Then I realized that had not been needed, it just pulls of the the 3 pins it sits on. Bad news is I didn't immediately put the cap back on, can't find it now, and its absense enabled the three prongs to come loose from the body of the connector.
Those of you who saw my thread about maybe putting a much newer drivetrain into my SDL might have guessed that I wouldn't be able to resist the lure (I'll post on that thread soon) so my buddy is going to be reattaching that line to the new IP. No good way to know which wire goes where. Maybe he could suss that out, but I'd like to do it first, it's not a trivia item he needs to deal with. I'll keep an eye out for a boneyard 603, not that common. There's an '87 300TDT with a 603 in Richmond, but it's been there since January. Who knows, I might get lucky, if it's the same fitting would have the same colored wire, I could just solder it in.
Here's an IP pic I found with photo of terminal, for another perspective:
