Default Chevy Colorado V8 swap Wiring help

hey guys, so im trying to figure out the wiring aspect of the swap. I have a 2005 lh6 from an envoy, im trying to put inside 06 Colorado, have the wiring harness pedal , pretty much everything to make its work... I started at the fuse block. pulled up data sheets for both. I can't figure out where the other pins will go or if I even need them to start. I want the truck to be able to pass smog and the dash to work. I've been also figuring out what wires from the blue plug from the lh6 needs to hook up to the blue plug from the Colorado. am I missing something. also figuring out what I need from the engine harness to I/p harness. and where those wires need to go
blue connector by the e40
