2003 chevy tahoe lm7 5.3 vin t.
I am looking for the wiring diagram for the alternator in this vehicle. It is a 3-wire connector. Two wires go to the pcm (green 15 and green 75). The third [blue] wire is a mystery to me. It may go to the charge indicator in the vehicle. I don't know.
Thank you

Pretty sure my 2003 Silverado 2500HD (Vin U) has a blue/green PCM. Was this just a typo, or is it the same?
Edit: Looking at Lt1swap.com, they list it the same from '03-07. I'm going with typo.
To make sure I got this right, CMP is Cam Position Sensor, and CKP is Crank Position Sensor, right?
Is "Low Reference" ground, or 5V or ???
Thanks. Hoping to get to my harness soon...

Hey guys, - I really need PCM pinouts (e67) and as much wiring diagrams as I can get for a 2006 CTS-V with the 6.0L LS2. I have a no start / no comms issue going on and my trans and coolant temp aren't showing up. PCM was tested good, doing same thing with two PCMs. Might chase BCM next. Thank you!
