I replaced PCM, battery and alternator. Drove to AutoZone and back car was dead in morning. I have three wires red orange and yellow/gray I’m not sure what order they go in for alternator plug. Can’t find a diagram anywhere.

Hello,

So just to clarify, the alternator is not charging the battery? Did the battery light stay on during your drive home?

I have attached the pinout and the wiring diagram below.
It shows the color and the orientation of each wire.

Please let me know of any questions.
Thank you.
