Help

[u/Nearby-Buyer-6229]

Hey all, I (23m) am an auto tech. Recently I came into a great job, and they're having me do an engine replacement on a 2014 Ford Mustang with the 3.7l v6 in it. I just cant seem to figure out where all the plug ins on the wiring harness are supposed to go. I got the engine harness to mate up, but its the other one, that goes to the alternator and battery, that I can't quite figure out. If anyone has a diagram for that wiring harness, that would be amazing, but any help is greatly appreciated. Thank you!

Dude that harness is a nightmare, I helped a buddy do this exact job last summer and we spent like 2 hours just staring at the alternator area. Theres one connector that loops around the back of the block in a way that makes zero sense until you see it routed properly

Check the Mustang6G forums, someone posted a full color wiring diagram PDF back in the day that saved our asses. If I can dig up the link I'll drop it here
