Default Tutorial: Obd1 Main Harness Conversion For 86 Hatch

Okay im working on dropping in a b16b into a 86 hatch Si. I decided to convert my main harness from OBD0 to OBD1. That means i went and pulled out a EG main harness. I got the whole thing. I couldnt find any 5 speed coupe civics at the salvage yard so i pulled one from a 5 speed 94 civic LX sedan. Finding a coupe could have save me from having all the wires for ABS and power windows and locks. this is my first wiring project ever, im totally new to this. i know that i jumped in the deep part of the pool, so i need some clarification and help so i can finish this project. and i hope that with your help this is going to be a tutorial for other people that wish to do the same to their 86's.

so far i think i got the ignition switch figured out. here is what i got:
