I really can't make a DBW schematic any easier than the factory service manual. If you already have the engine harness in the truck and it's running, you should be able to hook up the 3 wires from the TAC module to the cruise control lever switch along with a power and it will work. In this schematic, the wire on the far right where it comes out of the 'Fuse Block-I/P' and is labled 'VEH STOP fuse 15a' (f9 c1) this is the wire you would hook to the brake light switch, on the side that is hot (12v) when the brakes are applied. The TAC has to see a ground through the brake lights on this wire, so if you don't have any brake lights, it wont work. I fell for this myself before I put the bed on my blue truck, and then I remembered I needed brakelights!
If you have any questions, just ask and I'll try to walk you through any problems that you may have.
