so i have a 1995 cx (eh2) that came with a a d15b8/p05-a02 ecu. I have swapped a 1998 gsr drivetrain (b18c1) into the car, engine, trans, axels and all and am down to the last few things. i have a few questions about wiring that i cannot seem to figure out despite reading all the stickys a few times over. so i have two ECU's right now and i dont know which one i should use, i have a p72 a02 that came with the engine and then i have a p28 a01 (presumably off a obd1 del sol). now the code off the ecu that came with the car is A02 but the wires are OBD1 (three plugs two rows of pins) and the engine is OBD2, the towers were plug n play, i wired up vtec to the plugs under the dash , but i was a little confused about where the IAB/other three o2 wires are supposed to go and don't fully understand if i need to switch injectors, distributor and alternator. can i get a connecting harness and just run the obd2 p72 ECU?

i do plan on eventually putting a turbo on the car and want to run hondata so I'm thinking i should run the p28

let me know if i need to clarify anything, sorry i feel like this has been asked a lot I'm just kinda lost after reading so many forums
