Just got my 93 eg hatch with a b18b1 works fine except my check engine light is on upon closer inspection i seen that my o2 sensor in the down pipe is unplugged. i cant see a connector, so i took a look at all of these threads and i see that i need to do some sort of conversion. Please help i read that i might need to wire it directly to my ecu? if this is true does anyone know of a diagram. Please help!!!!!!

 

by "threads" do you mean wires? what are the color are the wires coming out of the o2 sensor?

 

You can buy a high flo cat with a connector for the plug im pretty sure, im not 100% sure tho..

 

By threads i mean that i searched through all of the forums

 

the 02 sensor is there and it is mounted in the down pipe there is just no connector from the wiring harness to plug it into. What i think i need is to wire it directly to the ecu. Does anyone have a pinout?
