magnum manual swap

hello guys! looking to begin a new adventure with my car. I'm thinking of a 98-02 Magnum engine with a T5 bolted to it. i want to keep the fuel injection and make it as low budget of a swap as i can. the things i would like to know are how the wiring of the ecu to the factory harness goes, and if anyone would be kind enough to write up a walk through on what i need?
