I used some terminals like that last year when I had to use an American Auto Rewire kit. The little cut part of the spade is what keeps the terminal in the molded plastic housing. Auto rewire might be able to sell those individually.
One time I was looking for a special connector and found it in a catalog that my local napa store had. I'll look and see if I can get the name. They had all the pin terminals like the oem stuff also.
my signature lines...not really directed at anyone in particular..
BE different....ACT normal.
No one is completely useless..They can always be used as a bad example
