I'm looking for an image of the ECM pinout. Specifically the Fuel Pressure Regulator circuit. I'm trying to trace down some wiring issues and can't seem to find it.

Thanx

Nevermind.... found the issue. Customer swapped the pigtail on the alternator with the pigtail for the FPR solenoid. That was fun.

Good find. I didn't even know they were swappable.

Yep, 2007.5+ alternators use the same Bosch BDK 1.2 connector that the fuel pressure regulator uses. 2007 and earlier use the traditional 4-pin plug thats been used forever.
