First off this site is awsome when it comes to the amount of information I've been able to find. The only problem is I seem to have is my swap is not the typical gen 3 harness and computer. A little back ground on the truck, it's a 96 was a 350/4l60 originally now it has a 2009 5.3 with the e38 pcm transmission was also used from the 2009. The harness and ecm were set up as a standalone from an unknown source I do know the guy who did the harness did not install it but I also do not have a pin out of how it's done either. Couple that with the fact the stock harness is still intact in the truck just laid over the inner fender, it's somewhat of a wiring nightmare. Has anyone deleted the stock black box computer on a 96 and run a standalone in its place? Before you say repin the 96 harness that's not really an option as the previous owner (the 1 who started the swap) has already cut off plugs and some wires at the factory computer. Is there a short run down of what the stock 96 computer controls? Any help would be extremely appreciated.
