H22a swap!

Hey guys I'm kinda new to this whole forum thing but I just need some help with my build. So I had a auto 00 lude which got converted to manual and swapped with the h22a and lsd trans (euro r).
Because the body was in such bad shape I bought another 00 silver lude with a blown h22a4. Now I am looking to go ahead and put my h22a into the new prelude but once I took out my h22a out my old lude I see a bunch of hacked shit lol. The whole wiring harness has been cut and adjusted I guess u can say. I guess the reason being is that it's a full h22a swap like I got the same injectors and throttle body and same distributor which I am reading now shoukdve been swapped over from the h22a4. Now I am wondering is there a clean way to do this job? Meaning keep everything that I have from the h22a (throttle body, injectors etc) but get rid of the hacked wiring harness. Also I'm pretty sure I have a obd2 ecu but it definitely does not act like one. Any tips feel free I really appreciate it!.

Should be able to swap the good harness over and switch these parts if you still the a4. Found on this site https://www.google.com/amp/s/www.pre...83010/%3famp=1

Moved over the following from the old H22A4 motor: a) Wiring Harness (OBD-II) b) Distributor c) Coolant Thermostat Housing d) Oil Pump Housing e) Crank Position Sensor and Top Dead Sensor (attached to OBD-II oil pump) f) Exhaust header (JDM 4th Gen is different) g) Intake manifold (if not using 5G IM, then move your fuel injectors over and get a 4G MAP sensor) h) Knock sensor (BE VERY CAREFUL TAKING THIS OFF, THE CONNECTOR BREAKS EASILY) i) Oil Pressure Sensor j) Oil Pan & baffle k) Oil Pan/Transmission Stiffener l) Various gears from the timing belt side (crank gears especially - required for CKP/TDC sensors) m) VTEC solenoid pressure switch (the connector seemed to be different on the H22A one?
