Default mpfi conversion help

hey i'm about to buy a 90 dx hatch because my crx is totaled and i was wondering what i need? i'll be taking the parts off of my totaled si so i already have everything, (i believe). i know i need the manifold, dizzy, ecu, injectors, fuel rail, resistor box. i'm gonna be swapping in my engine from the si so it'll have all of this with it. i need to know exactly which plugs i need and what kind of wire hopefully with fully detailed pics. i'm gonna have a weekend to throw the si engine in the hatch and get back home, and i plan on partying during the night time so i need to know exactly what i need and DETAILED instructions on how to do it. Tia

btw i searched and nothing really detailed came up.

i did search and came up with nothing really detailed. i've never done anything with wiring before and can't screw this up. i saw 4th gen hatch's site and that write up is decent. what plugs do i need exactly?, just the dizzy plugs?

you going to need the dizzy plug from the si engine harness. the injector plugs and all that good stuff, the resistor box with the plug. and ur going to have to run 4 wires into the ecu 2 for injectors and 2 for the cylinder postion sensor i believe. Make sure you shield the 2 injector wires really good becuz u will get risistance and throw a code if u dont do that.

Just ask some questions of pm me..ill help u out easily.
