So I just purchased my my first lexus less than 2 weeks ago. It's a 2008 ISF with 75,500 miles and of course immediately became attached to it. Unfortunately 500 miles later my battery light came on and I traced the issue to the alternator so I pulled it out and just had it rebuilt. The only thing keeping me from getting this thing back on the road is the plug that is right next to the power cable. As I was tugging on the plug to come off the alternator I unfortunately ended up with the wires in my hand but the plug still attached to the alternator. Completely my fault and every wire came clean out of the plug so I have no idea which wire goes where. It's a 4 pin plug with "green with white strip", "white", "pinkish (?)", and "yellow/brown (?)" wires. Does anybody have some sort of diagram or maybe even a picture of this plug with the wires that I can use to pin point which wire goes where? I have the tools to fix the wires that is the least of my worries I just need the sequence. I ordered a pigtail thinking it would come color coded but it unfortunately did not.

There isnt much info on wiring for this car and the little bit I did find does not have any information on color coded plugs. I contacted several local alternator shops but no luck with a diagram. They just offer me the pigtail which I already have. Any help would be appreciated this is the only thing holding me back from getting the car back on the road.

 

I can try to see if I can get you a picture of mine how it is in the car. Some users had paint for access to the Toyota website where you can download various service manuals for the car. Some users have actually ordered the physical manual set fyi. There are like 4 manuals you can buy but they retail for about $1k .

 

The connector probably got hammered. P/N 90980-11964 is the replacement part. Wires are numbered and positioned in the diagrams below - ignore the black wire, it is on a different connector:
