I bought a 97 civic with a gsr swap in it and its throwing a code for the o2 sensor. It came wire tucked and I can't find the connector for it so I tried to wire it to the ecu with no luck. Correct me if I'm wrong but denso blue wire is signal, white is ground and the 2 blacks are heater wires. I found the ecu diagram from ffsquadtech. Any help would be greatly appreciated!

 

are you looking for the pinout ? it's a bit hard to understand from you'r OP obd2 to obd1 via a jumper ? or obd2

 

I saw a pin out on one of the threads here for a motor build. And yes I have the jumper to obd1
