Just be careful to get one that has copper lead wires and not aluminum. As I mentioned above, copper and aluminum don't play well together. Your car harness is copper.
Help! 2010 Nissan Altima Alternator Pigtail
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.

my vin is 1N4AL2AP9BC114413. Is the wiring going to be brown, green, yellow from radiator back?Just be careful to get one that has copper lead wires and not aluminum. As I mentioned above, copper and aluminum don't play well together. Your car harness is copper.
Got her up and running. Thanks so much for your help.Correct.
You're most welcome, happy motoring!
hey bro im having issues with the same exact thing.. my vin is 1N4BL2AP5BN431792Shoot me your VIN, I'll get you the exact colors for your MY.
thank you, my friend. i really appreciate it.This is the view as you're looking down at the alternator from the front of the car. The only difference from a QR25 is that your middle wire is Orange instead of Green.

Hi I have the same problem. Could you send me a diagram. It’s a 2010 Nissan Altima 2.5 l
Same diagram as above, the '10~'12 sedans are all identical.
That’s the thing, I tried the diagram above, but my car hasn’t been starting and I’m assuming it’s a problem with the alternator. So I checked the pigtail and found the connection wasn’t secure. I got a new one and changed it but nothing. Idk what to do at this point.Same diagram as above, the '10~'12 sedans are all identical.
It's easy enough to tell if the alternator is the problem. Get it started with a jump and check the voltage at the battery, if it's 13.8V or higher then it's charging and your problem is something else. Most of them run about 14.2~14.5V. If it's lower then check the alternator fuse in the Fuse & Relay Box next to the IPDM. If that fuse is good and has power, check for power at pin 3 on the connector. If that has power then your alternator is shot.
Aquí tienes. El diagrama es "lado del arnés", por lo que está mirando el lado donde entran los cables.

Marrón 2, Verde 3, Amarillo 4 son los colores regulares para un 2.5. Los 3.5 son Marrón 2, Naranja 3, Amarillo 4.
