hey i just got a 91 civic hatch about a month ago and decided to go the b16a1 swap and i wanted to go obd1 and i didnt know where to start and i was hoping someone could help? could anyone tell me what ecu and what harness i need to get for everything to work properly and maybe a place where i could get it.. sorry for the stupid question im new to honda's.

 

as far as ecu i would go with a p 28 re-programmed to dohc. if your harness is already mpfi then your good all you need is a obd 0 to obd 1 conversion harness or else you are going to need to convert it your self. also you will need an obd 1 distributor, and the injectors with the clips are not needed but if you do you will have to remove your resistor box.
not 100% anyone can correct me if im wrong
