TBI - Actually, I found someone in the pirate board who gave me all the color codes, wiring info and location for whatever I need to do to get my engine running. I will write something up later on that. Thanks 
I think those have a seperate harness for the engine which made it for a easy switch from the 94 Blazer to the 84 Nissan. I may still have the complete GM manuals on the 94 Blazer/pickups if that will help.
