Dc header wire issue
 

I have a d16z6 and bought a carb legal header to pass smog. The issue is the wire from sensor was reworded for odb2 when my card is obd1. Any ideas on how to fix this issue

get a new 02 sensor that is meant for your vehicle? I'm pretty sure that obd1 and obd2 o2 sensors are the same as long as they have the same amount of wires coming out. I have seen 1 wire, 4 wire, and 5 wire o2 sensors in my day. Put an obd1 computer into my car along with a complete obd1 swap harness, left the o2 sensors in and had no problems.
