Alternator Molex Connector

[76 Yota]

Does anyone have a picture of a 2TC alternator molex connector? I'm trying to figure out if the E(ground) is part of the F & N molex connector, or if the alternator grounds itself via the bolt to the block. I have the stock conncetor, but its so old and cruddy that I can't tell if it has a third wire that was sheared off.

 

The molex connector I did pick up is for GM cars, but its only a two prong connector and not a third. Funny thing is it fits perfectly into the alternator. Stock is on left.

 

Stock connector fitted to alt. You can see the E male spade rests against the stock connector. If I rotate the molex 180, it won't insert completely into the alt.

 

New connector fitted to alt.. You can see the E male spade rests against the stock connector too. If I rotate the molex 180, it won't insert completely into the alt too.

 

So this makes me wonder if there is a ground wire from the alt. at all.

 

If there is indeed a third wire that needs to be connects, no one here in the states(that I can find anyway) sells a replacement 3-prong molex connector, so I was planning on just using a female spade connector with a #10 to the block.

 

**Edit**

Just found a three prong molex connector... new question... Where does this ground to? The wiring diagram just shows and earth ground, but does anyone know at what point it actually grounds to? Trying to save the trouble of cutting the stock loom and following the wire...

I think all alternators earth thru the bolt holding it to the block. I don't think the 'E' pin was conected to anything, judging by your pics..
