explain this. i have a 94 civic hb vx with a d16y8 comeplete swap. the motor is still obd2 and the car is running obd1 with a p28 ecu. i wired in the 4 wire o2 today and i just have a code throwing 41?

the 2 black wires from your new o2 sensor go to (1)A6 on the ecu while the other (2)splices into either a25 or b1 on the ecu

there are other ways of wiring it to where the harnesses meet at the shock tower, but i cant explain that unless we are infront of the car or the manual. which i have and you do not
