89 mazda b2200 carbureted to fuel injection, distributor to EI

i am the owner of an awesome 89 mazda b2200. it was a new vehicle for my family, and my first truck when i came of age. i spent a lot of time customizing the apperance of this truck, and even rebuilt the engine and transmission. The next thing i would like to do is to convert this carbureted, solid-state ignition system to an electionic ignition fuel injection system, but i don't know where to start. I need some advice for this undertaking. i don't mind going from junkyard to junkyard to pick up parts from other various mazda motors, and have access to a machine shop that can make custom adaptor plates if needed, and i am capable of reading wiring diagrams to retrofit any new computer connections that may need to be done.
