Thanks for the wiring diagram Eric. This option may be a little over my head so I need to get some more details on reprogramming the PCM and replacing the alternator with a 2004 or earlier one like Clinebarger does.

I will have to decide based on what I learn, which route will be the best one for me with regards to my abilities and if I can find someone in my area that can reprogram my PCM.
