Check out faxonautoliterature.com. They have an assortment of literature that should be able to get you up and running. There are original GM dealer service manuals for both vehicles which would have complete wiring diagrams. They list a separate wiring diagram book for the Camero. They have 2 different books on swapping newer GM engines into older GM vehicles. I've used them before and had excellent service. Hope this helps.

Installing a Dual XDVD276 radio in a 2005 Chevy Impala without the factory end of the wiring harness.
You will need to splice the wires as it will be hard to find the right connector to attach to the harness wires. Use the wiring diagram for the car (get it at Alldatadiy.com) and the one that came with the Dual unit to figure out which wires connect to each other.

Where to find diagram for wiring harness for 85 chevy suburban?
You can check out your local auto parts store for a Haynes or Clymer repair manual. I know that AutoZone, O'Reilly's, and Advance Auto Parts all carry these manuals at a cost of $20-$25. They contain the wiring diagrams for the major electrical systems. Unfortunately that's probably going to be one of the few sources for a vehicle that old. I happen to own an 85 Chevy Silverado 1/2 ton. What type of problem are you experiencing? Perhaps I could assist you.
