I have been looking at your question from time to time as I answered others.
I was kind of hoping another expert might shed better light on it.
So far I have not found the 4 pin system in any diagram for your year.
Do you have any idea what the 4 pin application went on (year, vehicle. Etc)?
I guess the next best thing would be if you sent your VIN so I can get the correct diagram for your truck out of "Prodemand".
This would show exactly where the wires go.
After seeing your latest postings, I cannot figure out why you did not replace the alternator with the correct one and everything would have fit back with no modifications or "McGyvering".
Maybe it was an emergency? Maybe it can be swapped for the right one with no major money lost?
I will try to help, if I cannot, I have a lot more experts here I can rely on for assistance.
