i have a 91 b18a1 which is obd0 how do i switch it over to obd1 so i can put it in my 94 civic hatch.

 

obd1 dizzy , 4 wire O2 and a obd1 ls ecu......and obd1 injectors.

 

He doesn't need the OBD1 injectors. He can run the OBD0 injectors, but will need to keep the resistor box. Don't forget this CLICK

 

jsut less of a hassle...if he runs the Obd1's he doesnt have to wire in a resistor box as it is going into a obd1 civic...

 

 

whether he uses the obd1 injectors or not, the jkobd harness is a must have. not just for this install ( which is a major fucking wiring mess without the harness), but if you ever add shit to your wiring (like an a/f meter or uugh:vafc hack uke) this allows you to avoid cutting into the stock harness.

Jason, when did the harness get the quick disconnect for the vtec and the o2? That's a sweet addition, would have come in handy when I did mine.

 

You guys dont understand....he said he wants to put a OBD0 LS INTO A 94 CIVIC...No harness is needed. He wants to convert the MOTOR not the car...

 

good catch, anytime I hear obd0-obd1 I automatically picture the car as obd0.

That said, o2, dizzy, injectors ( just to avoid rewiring the resistor box into the car), obd1 ls ecu.
