Hey guys, I am in the process of swapping in a B18C(OBD1) into a 99 civic si(OBD2). using obd2 EWH, w/ the obd1 ecu. any links out there of what plugs are needed and what needs to be cut/resoldered, plugs changed, etc? pics would be cool!

I already have the IAB sensor wired to the ecu. distributor, injectors, starter, altenator, and IAT are all taken care of.
After comparing both of the Service Manuals, I found that these are the only sensors that get switched...

all help is greatly appreceiated!

since your keeping it obd2 you might need to hook up the CKF sensor thats on the oil pump..obd2 motors have those and obd1 dont have that

 

im running the obd1 ecu as well, sorry.

 

everything should plug up and you will have a few left over plugs since obd1 motors have less sensors than obd2..also u will get a obd2b-obd1 jumper harness for the ecu.

 

yea, i still gotta get one of those! thanks for reminding me!
