i have a 91 crx hf with a d16z6.it has been converted to mpfi and it has an obd0 to obd1 jumper harness but the ecu is a p75 ls ecu(i did not do the swap)....ive had some problems with the trans and just put a different one in and now is leaking so i just want to swap it all....


would i be able to swap an obd1 b18b in and use my harness since its runing obd1 p75

thats a pretty good write up but now a lil confused on injectors i would just use obd 0 ls injectors and leave resistor box alone rite?

 

If using OBD0 low impedence injectors use the resistor box. If anything newer higher impedence no box needed.
