i bought the jdm b20a and it didnt come with the ecu connectors to the engine. the b20a i believe is obd0 (1988 model) ecu has 2 black and 1 big green plug in and the old b21a1 has 3 black connectors. can i get any obd0 connector from any dohc honda motor? if so will it work as well as the oem connectors? can i use the b21a1 ecu? if so then what changes would have to be made to make this run properly?
