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.




I purchased an alternator clip from the dealer for an 02 alternator.
Part # 15306329 $14
It came with two wires coming out of it. I wired one to the stock 99 brown wire and the second to the new wire I had run from the pcm.Plugged it all in and No more flashing battery light


Sorry the update took so long i havn't had much time lately.


So it looks like for now to get rid of the light you have to run a wire from terminal 52 (red) to the terminal next to the factory wire on the alternator harness.

Thanks allen for the clip
