Default ASAP help please on alt wiring

This is a very quick fix if someone can help me out. I have been searching and couldn't find a picture to help me. On a 2000 gs300, the 3 control wires for my alternator popped out when moving the alt for the water pump replacement (straight out of the clip on the alt. itself, and I have no idea what order they are in). There a wht/grn, red/blu, and a pink/blu. To view simply lift the rubber cover off the clip and the three wires are right there. Looking at the alt, from left to right could you let me know the order. I would have this done already but I do not know anyone with a GS.

If you need clearification for what I am asking, let me know. I'm unsure of my wording of the problem.
Thank you very much for any help.

I had found one similar to that one. But it doesn't show the wht/grn wire. I'm not sure if the wht/grn is on the right or left of the rd/blu and pink/blu. Unless if I am color blind and it is wht/blu (which is pictured above), but my GF, her dad, and I all said it was wht/grn. Thank you though. I might be able to test the connection based on that and narrow it down.

Look at the plastic connector. Most of the time the letter designations are molded right into it. Look for the "S" "B" "IG" and "L".

OK so I went and looked at the Lexus Elec Wiring Diagram manual and this is what I found:



The crossed out wire is only used on the 1UZ-FE so you should not have it.

Here are the wires:

"IG" = RED/BLUE
"S" = WHITE/BLUE
"B" = BLACK/BLUE



I hope this helps. As with all forum advise use at your own risk. This is from Lexus though, not me, so you should be good to go.

Thanks! I will know at 7 or 8 ish tonight. We took the connector and put 4" pigtails in it so next time I wouldn't have this issue (and we gave the wires a better hold). Before I sodder them together I'll test them.

Ended up being Wht/Grn, Red/blu, Pnk/blu from left to right looking at the front of the alternator. Thank you for your help. It help narrow it down.
