T shaped plug for the back of an alternator

There is one of them "T" type plugs in a lot of pre-1990 engine compartments I have looked at in a wrecking yards in the last 10 years, just look around in a wrecking yard, they are used for distributors, oil pressure senders, alternators, even Kubota

This one is kinda spendy.

Here is another one, although you may have to cut off the clip that locks it in the hole.

I will admit that I cannot tell the size of the "T" plugs, but they look like ones that will fit on the Datsun/Nissan alternators.

Go to vintageconnections.com (??).  You will have to identify the plug VISUALLY on their website, as they do NOT have applications.  Good luck!

Go through a wrecking yard and clip one off a harness. Don't tell them they'll say no way or find a harness that's already savaged. Put in pocket and say you didn't fine one.

use 2 spade connectors. done and done
