97 bmw M3 Sedan. I'm running a Ls2 gto engine, with a ls1 wiring harness, and computer. The alternator wire is only a single wire from my ls1 harness, but the plug coming off the ls2 alternator is a 2 pin plug. Is it possible to use my ls2 alt with the ls1 harness and computer, and if so how? I have the charging wire coming off the alt, but it's only putting out 11.99volts. I have not test the Ls2 gto alt, but I am assuming it is good, only had 46k on it. Thanks for the help guys!

No one can tell me if a Ls1 pcm can run a LS2 2006 GTO Alt?

You can run the alternator no problem. What you need to know is how the alternator is wired. The LS1's from Camaros are wired differently than a GTO. I went to a 04 GTO pcm and it needed to be reprogrammed by changing the platform code to a Camaro for it to charge. For you since you are using a LS1 411 pcm (I assume) and harness you will need to wire it just like the LS1 with a single wire to the 'L' terminal only. The 'F' terminal is not used.

Yes sir, 2002 Camaro PCM, custom built harness, 2006 LS2 Gto Alt. The harness was built with a single wire for the Alt with a LS2 plug. What side of the 2 pin plug on the alt is the L terminal? Do I need the 470ohm resister in that wire? I have read countless posts, but can't seem to find a do it this way post for my setup. Thank you for your help!!
