i need help with converting all the obd1 to obd-0 or vice versa, i used the si harness and hooked everything up running off the si ecu but it wont start, all the threads i read are 90-91 b18s which drop right in using stock harness and ecu but i happen to have the obd 1 92 b18a what do i do!!! thanks all who help!!!

 

ecu conversion harness obd-0 to obd-1

rywire.com and boomslang.com both sell good kits and have great support/instructions on how to do it.

 

You used a 92 b18a in your crx with the 88-91 crx si obd-0 harness. Im guessing you also used the 88-91 crx si distriubor and oxygen sensor. Was the distributor in your other engine or can you guarantee that its a good one?? do you know if you have spark?

 

i have a 98 LS in my 90 civic, i used all the OBD0 parts and a white plug 90-91 LS distributor, it should run and start fine, LS ECU no problems

 

I got a 91 LS in my 91 Hatch, and I had to use Si wiring harness to make it run. The LS harness doesnt plug n play with the body.

 

thanks for all the help guys i ended up just buying the wiring harness from boomslang and overnighted it.
