I have a obd2b civic and engine wiring harness and I have a 98 jdm b18b!!! I'm currently running a p75 obd2a ecu and I have converted the connecters for the ecu myself ( and yes I have done the iacv switch)! Now obviously I'm having a problem since I didn't know that the 98 JDM engine was like a obd1 here! I was just able to put my hands on a obd1 p75 us ecu, now my big questions is: will a jumper covert the obd2a connectors to the obd1 ecu without further manipulations on my parts???

Really need help cause I want to avoid any further screw ups on my part!!!!

Thanks
