I got lucky and have a complete 2005 donor truck. So i have every wiring harness that came in the truck i was wondering if anyone had the pin outs to run this motor stand alone. I wont be using the 4l0e tans or np241 tcase. Im bolting up the SM465 and married np205. That is another topic im a bit foggy on too. From what i have read to mate the two i need a 0 or newer 6.0 flywheel a sm465 clutch (12 inch) a 6.0 pilot bearing and a throw bearing. Not sure if the stock starter will work on the 6.0 flywheel but it should.I plan on using the stock sm465 bell housing ill just be down a bolt hole.

lt1swap.com has a lot of really good wiring information, including diagrams for most years of truck Vortec engines.
