I believe its a 5 wire hook up if you use a stand alone pcm. Not 100% sure. I think that several companys also make the motor mounts for the ls series engines as well as transmission cross members. There is a lot of info out there.
"street Trucks" magazine (november 2009 issue) has an entire write up for putting a 5.3 vortec motor into an older C10... good information, wiring harness supplier etc. you might be able to find a website for them or get a back copy of the magazine.
