Chevrolet Repair: electrical, 1990 chevrolet caprice, monte carlo ss

Question
I need to know where to find an electrical diagram that will list each individual wire coming out from the fusebox going to the interior controls on a 1990 Chevrolet Caprice Classic Interceptor. Im putting the eng; trans, and all wire to make it work into a 1986 Monte Carlo SS. It originaly had a V8 but the 1990 is fuel injected. Thank You for your time.

Answer
In the back of the owners manual for the vehicle in question, there will be part numbers for all manuals related to that vehicle.
Or you can go to the public library, in the refference section. They have all types of manuals.
The service manual will give some info, wut a book on wiring diagrams is the one to read.
Mitchell manuals are usually very good for them.
