im looking for a write up on how to convert from obd to obd1 the ecu plugs are al ready cut so the pin numbers dont do me any good i have a 90 civic si with a jdm d15b vtec motor and a p28 computer a wiring diragram for a90 civic si would help out a lot to

 

well pardon my french but that was a pretty f*ckin stupid thing to do. Now you dont even have the plugs for reference to go off of. If you didn't cut the wires too close to the plugs and you can possibly reattach the wires to them, do that, and then do it the RIGHT way by purchasing an obd0-obd1 conversion harness. What posessed you to do this? If you dont have enough wire left on the plugs to reattach them then you've certainly planted yourself firmly in ***** creek without a paddle.

 

sucks gl tho

your fucked

start with a new harness, there are too many wires that are the same color but require different locations

 

lol that sucks *****

 

Rewire your plugs and invest in a odb1 jumper that plugs into your existing obd0 harness. Easiest way to convert.
