DIY HEMI Wiring Diagrams

I ended up buying the Hot Wire hot rod harness and computer. Hours and hours with the factory harness with no positive results and within less than an hour with the Hot Wire harness, the car was running! My issue now is that I want to use the Dodge Ram instrument cluster, but don't know exactly how to do that with the Hot Wire harness. If anyone has any ideas or suggestions, I'm all ears.
