Fuel Injection Wiring

can someone please help me. I am wanting to switch my 91 honda civic from dual point fuel injection to a multiport. I have a SI fuel injection and the si computerl, but am confused about the wiring. How do I wire it so it will change the wiring to work for an SI?

Even if someone can't explain how to do it, can you point me in the right direction to find the information. Whether it's a website, or forum, or chat.
