Hello forum from Las Vegas, Nv.

[Pioneer]

I actually have a 2004 Lincoln Navigator as I understand is very similar to the Expedition. My issue is the (battery light) and (check charging system) indicator. Battery is good, New upgraded alternater from 110amp. to 135amp., harness from alternator to battery and PCM continuity check good, new pigtail from harness to alternator.
I would like to verify the correct pin at the PCM. Can someone guide me to the correct (pinout) diagram for this vehicle ?
Also... When you upgrade the alternator, does the PCM need to be reprogrammed ? Very puzzled. Thank you.
