Here is the skinny.....

I have a 1991 1500 4wd 1500 burb. I lifted it with 1 ton springs and a 4 inch block in the back and installed a 3/4 ton rear end. It has a stock 700r4 tranny but the engine I have installed a 1998 7.4 vortec engine. But that's as far as I've gone. The harness and computer have been installed. And I have the interior dash harness from the 98....but I don't know what to do with it. I was told to change out the fuel pump to the new one but what else can I do....what do I really need to get this to work?
