Hard to say exactly from pics, as the opposing pins obviously need to be spaced right. The last one with six looks like what I bought. Every other thread here that I have read also used the six-pin as a start. i am sure I paid under $15 for mine, but that was over five years ago at least. There is a Toyota one that has two pins at hte right distance, but it is too shallow. It has to be a deep socket for ours.
