Hey, While working on my Altima (2.5) The plug that goes to the alternator broke. I bought a replacement, but am unsure of which order the wires go in. It's a 3 wire connector and the wire colors are Brown, Green, and yellow. I've looked all over and can't find any information with a car that has these color wires. Please help.

Shoot me your VIN, I'll get you the exact colors for your MY.
Here you go. Diagram is "harness side", so you're looking at the side where the wires enter.

So, that means it should Be:
Brown: closest to radiator
Green: middle
Yellow: closest to engine

That's the way I was going, but wanted to make sure first.
Yes, the polarizer faces the center of the vehicle so that would be correct.

Is there a way or do I need to get a new connector
Shoot, my bad. Didn't realize that's the replacement connector you have plugged in, sorry. Made me do a double take. Is this a coupe or sedan? The wiring is different and the VIN doesn't tell that.
That white-looking wire is bleached-out, it used to be either green (coupe) or sky blue (sedan). For the sedan, the wires will be violet to the bottom, yellow in the middle and the bleached wire on top (closest to the block). For a coupe, the order will be violet (brown) to the bottom, the bleached wire in the middle, and yellow on top.

Sedan
Then it's violet, yellow and bleached, from bottom to top as you're looking at your pic.
