just swapped a 92 ls motor bolted to a 95 ls tranny in a 96 civic coupe(still using stock harness). bought the hondata s200 installed in a pr3 ecu from some guy. the stock harness wont plug into the ecu what do i need to do ,or i justed wasted my money. also what ecu is that

 

means the ecu u have with hondata is obd2.

Wrong, it means its most likely OBD0 since PR3s are from 89-91 JDM B16A EF8/9
or 92 JDM Integra B16A EF8/9.

What you can do is buy a conversion harness. I never really heard of one but they might make a OBD2a to OBD0 one, but I'm not 100%

 

would it be better to fine the conversion harness,or just swap out the hondata into a obd1 ecu. will i be able to tune and run the car properly with the obd0 ecu,if i can fine the harness

 

bump

 

ok heres the thing the pr3 does come in two obd forms obd1 and obd0 neither of which are good for you beacause thats a vtec computer your gonna wanna go with a obd1 p74 or p75 those are both from a 94-95 integra ls obd1 you can also use a pr4 obd1 from a 92-93 integra .. however either route you are going to need a jumper harness for obd2a to obd1
make sure its an obd2a and NOT AN OBD2B
obd2a came 96-98 and obd2b came 99-01 so be carefull also i have the p74 already chipped with a 8000k revlimit and its a mugen program if you are interested in that let me know in a PM however the conversion harness look on jdmshit.com or any of those sites they are typically 75-100$ shipped
