nelson 02 pcm in my 99 update

First off for the new guys I have a 02 Nelson Tuned pcm in my 99 Step side.
Bottom line without getting into it, I did this because it runs alot better than the 99 ever could.
The only problem I have is the flashing battery light and dtc code "Generator Terminal F circuit"
Looking at the wiring schematics between the 99 and 02 the only differance I found was an additional wire from the pcm Red terminal #52 to the alternator.
Terminal 52 is not used on the 99 pcm.

Well thanks to Allen I got a pcm clip and finally added the wire to terminal 52.
I ran it up to the alternator and now I'm only waiting for a new plug (02 plug on order) to plug in the alternator. The 99 doen't have a slot for it so I can't just add the wire to it.

If that doesn't cure it there may be a missing wire in the alternator itself. i tried taking the black plastic off the back but couldn't see if there was two wires or not. I ordered a GM 145a alt because I needed one anyway so that may have the upgraded wiring.
The next step after that is scaning the nelson pcm and picking up the vin and ordering a 02 bcm. the dealer is going to have to flash the new bcm with the vin from my 02 pcm.

Should know in the next few days when the plug comes in.
